Hi,
I would peg your chances at middling, that is around 40-50% chance admission. Your scores are nice and your awards are amazing. Unfortunately, Ivy League/Stanford/Caltech receives floods of Chinese/South Asian applicants who are interested in and very good at the STEM fields. You might be able to improve your application by focusing on extracurriculars – finding a way to stand out from the pack and tell a great story about yourself.
bump!
Nice AIME score - although I’ve heard the cutoffs were rather high this year. Must be bad to score a 10 on AIME and not make USAMO 
I agree with mellycx; what else interests you?
