If you're drinking beer or wine it is certainly very calorie dense. You're looking at 208 kcal per pint of beer or 123 kcal for a 5oz pour of wine. A pound of fat takes about 3,500 excess calories, or 16 pints of beer. So if you drink 2 a day all else equal you could gain nearly 1 lb a week.

This is just pointless ceteris paribus because genetics are the biggest variable.

If someone has a predisposition to diabetes they can't drink alcohol and hold things ceteris paribus because of the way alcohol effects the liver and then effects insulin.

Insulin sensitivity gets worse, blood sugar is all over the place and then the person is on a rollover-coast of over consuming calories to try to stabilize blood sugar.

IMO your post is why almost all dieting advise is just complete oversimplified nonsense. Meaningless ceteris paribus linear combinations that mostly add up to a non-reality for a non-linear complex system. It is a way for people to pick and chose what they want to be true.
