Learn as much as you can about computer graphics any way you can.
Do a google search for "computer animation courses." There are many choices.

There is nothing to prevent you from creating your own games now, either to sell to the gaming industry or to prove your talent for it when the time comes to look for a job. Unlike most lines of work, making computer games is a job where being young is an asset. You have a better feel for what young people want and the ultimate goal for those businesses is to make products that will sell.
