My aunt believes in this theory, about extrapolating from blood types. I don't, but can keep an open mind-no need to argue/debate. Whatever works for a person is fine by me.
I think of it as being akin to astrology, in that there are no "good" or "bad" signs to be (categories to which one belongs)-each & every one will have pros & cons.
Mine is O+ and she tells me that means I'm at risk of clotting (too much, I presume) problems eventually.
She also claims it means I have high(er) level of stomach acidity and should therefore eat meat (which I do anyway), can't recall what she said to avoid (bread/carbs?)- though it doesn't matter, since I'm going to consume what I like regardless of whether these guidelines advise for or against a given food.
"O" really means "zero"---your blood has zero factors in the ABO category, and the "negative" also means "zero" so you have no factors in the Rh category, either. Therefore your blood is completely neutral, and anybody else can take it. You are the universal donor to others, which means your blood type is in demand.
But, that also means you can only receive O negative blood yourself, for you cannot have any factors at all introduced into your bloodstream.

While O Neg is the "universal donor" it isn't in any more demand than other types and in less demand than more rare types like AB pos or neg or B neg.
The idea of a "universal donor" is overplayed, while true in theory not really in practice. When blood transfusion is required unless there is an extreme emergency or shortage blood given is always matched type to type.
AB neg to AB neg
O pos to O pos
A pos to A pos and so on
I worked for several years as blood bank technologist before going on in school and I can remember exactly two times I had to type and crossmatch O neg blood for a non O neg recipient, both were massive trauma cases where the amount of blood needed outstripped our supply of the correct type.
