Correct with abs you use gentle pressure on the brake pedal never slam on your brakes if driving in winter conditions. If you pump on your brakes to much that’s how you develop out of round rotors also even pressure only.
No. With ABS in winter conditions (or any panic stop for that matter) you use as much force as required on the pedal. That required force is not always gentle. That's how ABS works. You give control to the electronics because they can control the slippage much better than you can.
Unless you meant to say without ABS, which I doubt. Out-of-round rotors are a small price to pay for not hitting something with your vehicle.
How to use four-wheel anti-lock brake systems:
Slam on the brakes. ...
You may feel the brake pedal vibrate and hear a clicking sound – this is normal.
DON'T pump the brakes (this will deactivate ABS).
Keep your foot firmly pressing on the brake pedal.
Keep steering to enable four-wheel ABS to work properly.
It's surprising and a little disappointing how much confusion there is here.
I agree with those who say to stomp on the brakes and keep your foot on them and let the ABS do it's thing. DO NOT try to pulse your brakes.
My best advice for winter driving is to PRACTICE. Find an ice covered road with little traffic on it. Drive a little faster than normal and practice slamming on the brakes to get used to how the anti lock brake system works.
If you can find an empty snow/ice covered parking lot (or a frozen lake if you live in a place like I do), practice skidding and going out of control. Gain some skills for how to pull out of skids and spins.
I firmly believe that driver's ed would be much better if they made people do stuff like this before letting them get their licenses, but I know it won't happen.
Once again, ABS is there to help you, but only if you let it. If you need to stop hard, do NOT pump your brakes. Step hard and keep your foot there until the car stops moving.

A gentle reminder here that your brakes can only stop you as quickly as you have traction to stop. Ultimately, it's your tires that do the work. Don't cheap out on winter tires or you'll find yourself in a ditch.
Press firmly on the service brake, don't effing stomp on it. ABS is always active nomatter how hard you press, it's not a substitue for proper driving You stomp on it, you will lock the wheels up... and there goes whatever traction ABS could've found. Often ABS and T/C work together ams nearly act on the se accord. And manually pulsing your brakes causes out of round rotors? That's how ABS works. What you also don't want to do OP; is brake in a turn if you can help it. Slow the car down enough before the turn and don't power through it- coast. All the ABS, T/C, Torque vectoring and active aero is not a replacement for driver skill, they are aids. If the cars going to slip and slide, it's going to do it and you need to decide how to recover or wreck less.
For a good winter driving habit, ABS should never even kick in. Traction control - sure. Not ABS. ABS kicks in when it's already slipping.
You are correct when saying that the ABS should never kick in if you are driving properly (the right speed and so on), for the ABS and stability control come into play when one or more of the tires come into a skid condition. The ABS tries to avoid locking the wheel (s) that looses traction, and also becomes active as directed by the traction/stability control.
Both the ABS and in some automobiles the motor as well, take part in the stability/traction control. For example, on FWD automobile encountering a lateral skid during a turn, the ABS automatically engages to increase drag using one of the two wheels (depending on left or right turn), which in turn reduces the rear end of the car from trying to pass the front end of the car. Experienced drivers of the past would carefully pull the parking brake handle between the seats-without locking it-to accomplish the same action.
Nowadays is that the automobile takes care of all that for you, but in the past a lot of old times like me accomplished the same "manually." Also, most of us old farts could never accomplish the task as fast as automatically done by new automobiles.
When this WSS data is combined with the yaw sensor data and SAS inputs, the ESC will make calculations and start applying wheel brakes to correct the situation. This brake application could be a single wheel or multiple wheels, depending on what the ESC module feels is the best response using the available data.
If the vehicle is under-steering on a right turn, it may only apply the right-side brakes to assist in a right rotation. The opposite happens if the vehicle is over steering or fish-tailing on a right-hand turn. It will only apply the left or outside brakes to compensate and allow the driver to regain control. If the situation cannot be corrected using the brakes alone, the ESC may also cut the throttle, retard ignition timing, shut off injectors and even change transmission settings to intervene, all attempting to allow the driver to regain control.
ABS is not saving you from a panic stop, especially in winter.
With a choice of ABS or no ABS in a panic stop ABS is an absolute no-brainer summer or winter. If you disagree you need to learn how they work. They won't keep some idiot from pilling out in front of you (like I had Friday morning), but they will, especially in winter, stop you quicker.
And for anyone who has a car old enough to not have ABS pumping the pedal is correct on snow and ice.
And the poster who advised practicing in winter is 100% correct.
Just spotted this post by you and it tells me that you know little to nothing about the operation of ABS systems. Please refrain from giving out bad advice,

OP You cant do anything about ice.
No matter how you use the ABS brakes, the wheels will always lock up eventually on ice, if you cant feel them lock up, you wont know to let the pedal go and press it again. By that time its too late and you cant steer.
So my advise, if youre not confident enough to drive on ice, just stay home until it melts. Or call Uber so you can go to work.

Do you not get what "anti lock" means? I'll fill you in, it means that the wheels WILL NOT lock up on ice. It really shouldn't be this hard of a concept to grasp.

5. if you hit the patch and went into glide, do NOT brake. IMMEDIATELY shift into neutral. THEN do pulse braking.
You do not do pulse braking with ABS. Hold break pedal down, FIRMLY!
