How bad is every day drinking?

I know that alcohol is bad for your health period. But everything is comparable, I smoke every day, my parents drink everyday I just assume their lifestyle is healthier. When I tell people that my parents drink everyday idk how you keep so many bottles in your house full they seem shoked like I am a victim of alcoholism, but truthfully never ever I saw them drunk, because they would drink a glass of wine or a shot a day not enough to even become drunk. I am asking because I am 21 soon, and like alcohol too and don’t see anything bad can happen from daily wine drinking. Any experts knowing how bad it is or it is not a big deal?
