Whatever fine college you end up at probably won’t have a lot to do with luck. Applicants work however hard and achieve however much they achieve relative to other applicants, and then some very dedicated people (AOs) work tirelessly over a period of months to sort it all out.
I understand your feeling of uncertainty and the desire to figure out whatever can be figured out to remedy some of that uncertainty, but your situation isn’t fundamentally different from all the other applicants: Hardly anyone can know for certain what their outcome(s) will be. So do the things people have talked about here (if so inclined), but more importantly just keep working toward the most successful senior year you can put together (academically, athletically, socially, happiness-ly). Things tend to take care of themselves, in some form or another, for people like you who work hard (ok, sort of an oxymoron ; )
