They're not, hence exception. You'll always find an exception if you go digging, but that's the general rule of thumb. I don't know, it's not my rule, I've just heard the guys at Soxprospects say multiple times that that's the gold standard with the Sox player development on promoting guys. There's also certain things they look for as well, and I'm sure that number is fungible. If a guy is a little over 200, checks all the boxes of what they're looking for, and there's a spot in a level above them, they move.
