Wait Lists are rejections - that’s the reality. The schools didn’t accept you.
However, they are using you as an insurance policy, in case they don’t have as many enroll as they expect. You’re a quality student and they realize this - so they put you out there - but this is for them, not you. So they’ve said no to you but…we could change our minds if needed.
So to answer your question, there’s no way to know the likelihood of getting off but it’s likely not good - and you should not think about it. You should be focusing on where you are committing to.
If a WL comes through, you can address it then. But if it comes through, it’s more about who didn’t attend that they thought would (in aggregate #s) vs. anything about you (until they start choosing who to pull if they have a spot).
Obviously you’re a strong student - but please focus on who accepted you vs. these schools. Emotionally, you’ll feel much better and the strong odds are you’re going to one of those accepting schools.
Good luck.
