Your parents sound like smart people.
Do yourself a massive favor and try your best in school and get the best grades that you can. Pick up programming and tell your parents you want to be a programmer. It will give you an excuse to use the computer. Than you can get a job programming for a gaming company and you can play video games all you want BUT also be able to put a roof over your head. You might not reach your dreams of being an invite master of the universe, but you'll at least have accomplished something.
