That's pretty damn good writing for a 13 year old.
If you stay on track, you can do it. They key isn't just gong to every practice and working hard, it's the extra stuff. Going to camps and open mats is definitely the right thing to do, keep it up! Consider starting a light weightlifting routine if you want, if not then when you're a bit older. I don't know you, but I'm always cautious in advising kids to lift weights too much. 15 I'd say is a good age to start.
Also, so I don't have to make a new thread, would switching Muay Thai for Judo up my wrestling game? I've got friends who take it and they're fantastic wrestlers, the art in itself is also highly appealing. Muay Thai doesn't really do much for me expect give an alright workout, and some confidence in a fist fight. I mean, it's not like I'm training for MMA, so would Judo be beneficial?
I think you should look at wrestling as a year round sport if you want to wrestle for a D1 team.
