I don't mean to ruin your dreams, but the chances of you being an Olympian, starting at your age, is so close to zero that's it's not worth considering. Don't get your hopes up for something unattainable.
Instead, play your favourite sports, exercise daily, eat healthy, and practice and train consistently. You might be able to compete in a sport at a higher level than right now, and if not, sports are always fun and it's never time wasted.
