What chance do I have

Hi!
I’m in high school, and plan to do undergrad in an American University. Just wondering what chances I might have to get into a good college. I’ve been singing different styles of music for 5 years, have done piano lessons for 10 years including 4 exams at trinity college. I’ve also joined a couple of clubs in school. I took the psat and got a 1100/1520, not the greatest score but working on it. Other than that I take the IB curriculum, and get an average result. I do some community service through school, which I heard was important for admissions. I enjoy reading too. How much of a chance do I have to get into a good University? I’m very worried because I’m coming closer to applying.

Thank you!!
