Is it too late for me to start dancing?

I've been a gymnast for 10 years, made it up to level 10. I quit last year and tried diving, but didn't care for it. I'm 16 and I still have all my flexibility and leaps/turns/jumps that I've learned. I've always loved to dance and do well with choreography. I'd love to start dance but I'm worried i'd be put with girls that are either way below me or way above me. How does it work? Would I be with girls my own age? I'd like to compete. Any advice would be appreciated, I have no idea what this involves. Thank you!
