How people manage to play and chat online with random people?

This may sound dumb for some of you but I just can't play online, or at least I can't play anything with chat or a very social aspect. That's why I only play tekken on my xbox since that doesn't require socialisation but I have so many games and I feel half of them are worthless now that I finished the campaigns because I don't play them online.

People said "use discord" but that shit is so counter intuitive to use isn't like reddit, that just find a sub and connect. I don't like that you need invitations and that every game is subs inside subs and diverse chats... is too much.
