Am I being overly dramatic?

So I just wanted some opinions on what constitutes as a potential drinking problem. My parents drink about 5-6 beers everyday a piece and on the weekends it’s more like 10+ a piece. One of my parents has also gotten a dui. The other won’t go to any restaurants that don’t serve beer. When I bring this up they get really defensive but to me it seems like it’s a bit of a problem.

Am I looking into this too much?

ETA: I don’t drink at all, haven’t in 4 years just bc it doesn’t taste good to me so they look at me as a “prude”
