Yes they’ll happen. To whom, who knows. But to be on the “likely letter” watch is akin to watching paint dry. Spending even 2 seconds on this extremely unlikely happening is even wasteful, IMHO. Yes, some people will get them. So what?
And it might even be you? So what? Wondering about it now is a waste of energy IMHO. You’ve done all the hard work (getting in your apps). Now go and enjoy the rest of your senior year. You deserve it.
