This is correct, but, imo, incomplete.

The fact is, some of these groups kind of suck. Maybe they’re cliquish. Or maybe they are all dicks, or are judgemental about people who arent in the group. Or maybe they just aren’t your vibe for whatever reason.

If you are trying to make friends, I think the advise shouldn’t be “join a hobby or club for something you’re interested in” but “try out every hobby or club for everything you might be interested in”!
