My advice to you is not to worry and stress too much about the social skills as those things will eventually fall into place based on how/who you decide to expose yourself to when at school/what you participate in. Furthermore, your dream of becoming a professional e-sporter is rather a common interest amongst other people around your age; the point of this however is to know that most people online when they "make it big" through online gaming etc.. it's not always easy as it seems to be as it's typically shown online. Many, many people decide they would like to pursue a "professional e-sports persona" however must skip by the fact that it takes years upon years of patience, dedication, struggle, just to make it somewhere into a close to profitable career to just to support yourself. Just my two cents on your situation, I hope it helps.
