Is it possible to do sports outside of the college you attend?

Hey I’m a high school junior and have been boxing for about 3 years. It’s something I’m really passionate about and would like to continue into my college career. At this point I’ve given up on finding a college with a decent boxing team/club and have found boxing gyms that are close to the schools I wanna go to. But now I’m starting to wonder if it’s even possible to participate in a sport? Am I gonna be too busy for that, especially since it won’t be through the school? Idk I guess I’d just like to know if anyone else has managed to do an outside sport and balance it with their education and/or work. Any advice/stories are greatly appreciated.
