It's not really that different. I live in a rural area where you can't afford to stick to specific groups or you'll have nobody to talk to. I'm in my late 30s and my friends have ranged from 18 to 85.

To be fair the really younger ones were usually attached to a larger group but we still considered each other friends and would hang out and talk about... Well, the same stuff we talk about here online with age-indeterminate people?

Guys we'll drink and talk trash, mechanics, guns, projects, gaming. Girls more music, culture, many of them are into gaming or hunting/outdoors stuff too believe it or not.

Couple years ago I was sitting by a fire talking about AoE2 with a 19yo girl, I think the game is older than her but she got into it when Definitive came out on Steam!

I also have a friend in his 80s I go over for sauna and tea with regularly, he has so many wild farm stories and knowledge to share, plus he is an old school original coder and ham radio operator who is the last maintainer for an ancient database system.

You have something in common with everyone except the truly stupid, don't be shy and just talk to people
