What's my likelihood of getting accepted for Law at the university of Edinburgh?

I'm just a bit worried that my personal statement wasn't good enough because I'm also applying for art and english courses so it focused a lot on that, I really haven't done any law-related extracurriculars.
My higher grades are AAAAA, this year im taking advanced higher english and art which I'm predicted AA for- is it stupid of me to worry? I just have this feeling I'll be rejected but I'm curious about what subjects and extracurriculars you need to be accepted onto the course.
