This goal is extremely ambitious, and that's awesome, but it's not feasible (in the way you described) as others have said in this thread. If you want to fully realize this dream of yours, you should get a college degree in game development, not computer science. Then, you could work at game studios and built up experience. Eventually you could start your own game studio and create your game. This isn't impossible to do, but you can't do it by yourself.
