Why don’t Blood Transfusions clott?


Okay so if Blood Type 0 has no antigens and antibodies A & B, and Type AB has A&B antigens and no antibodies…

If AB gets a 0 donation, wouldn’t 0’s antibodies react with AB’s antigens and cause a clott?
Or does ABs immune system not understand that there is an issue because it’s not the system’s antibodies?

Very tired and drunk rn please help me get rest lol
