do online casinos actually ban winners or is that just a myth

I keep seeing posts and comments about people getting limited or flat-out banned from online casinos after a good streak, but I've never actually met anyone who said it happened to them personally. Some folks say it's only if you're using some kind of edge or if the casino is sketchy, others swear you can get banned just for running hot. With crypto casinos, it seems like the vibe is more anonymous but I’m not convinced they don’t track and cut off winners too.

I've pulled a few nice wins here and there on slots and poker, never anything high-roller level, but never got so much as an email. Are these bans mostly just scare stories, or is this a real risk if you start cashing out serious amounts? Anyone actually get limited or banned for just winning too much?
