It is kinda true unfortunately. People get super tryhard about so many games, and if you aren't into "getting good," then those games aren't gonna be as enjoyable. On top of that, those games are often only fun with friends who care about the game as much as you do. I don't play competitive multiplayer games anymore specifically because I no longer play with people who are into those sort of games.

If you do want to play a more casual multiplayer game without an established friend group, I'd recommend games with community servers that have a number of regular players. Those servers can be neat hangout spaces that you can join without needing to worry about how good you are at the game.
