life is cruel so you must fight to win
Also, if you start college/uni at 21/22 it would be nothing strange. There are many people who retake/change courses, don't go to college right after finishing high school or simply do a second course. It would be very likely you go to class with someone your age.
And finally, don't spend so much time on anime and vidya. It's escapism at this point. You can watch Kaiji because it will help you realise what happens when you loiter, and that's it.
