Can I still become a pro footballer/soccer player?

I live in the USA and I hate how Americans call the sport soccer, but I would dream of become a pro footballer. I have great grades and I practice everyday for about and hour. I started when I was 10 and this is the reason I am having trouble. Is it too late? I played for my school team for 2 years (and plan to make it 5 years) and I played freestyle for 2 years. I train through rain sleet and snow and most of the time, I practice all skills. Should I increase my practicing time? I'm not really skillful but i'm rigorously working at it. I'm now 15. Can I make it?
