I want to become a professional athlete?

when I am older I want to be a sprinter. i am in my athletics club at school and I came 2nd in all of our matches, 1st in districts, 2nd in counties (by a tiny bit), and 1st in sports day. My event for all of those was the 80m. I am 13 and so far have had no training whatsoever and my personal best for the 80m is 11.5 which was timed at a match. My dad timed me at sports day and I got 11.3 but I don't know how accurate that was. Because the term is over and we have summer holidays now, it means I won't be sprinting for a while. Athletics is only in the summer term so have to wait another whole year. But I do have these coaching sessions at my local club as a free gift thing that you get if you come 1st, 2nd or 3rd in your event in counties. Basically I would like to know if at this age I really need to be thinking about training or not? Is it important for me to start? Thank you in advance!
