lots of reading but help please

I am 15 and a sophomore in high school. I have made a few highlights on this account for the teams and players at my school. My school also has a thing where we live stream the sports games and events and stuff. I get paid for that and I know my boss well and am able to work a good amount. I love doing sports video, tv stuff, and working my job so I’m planning to major something like this wherever I go to college.

I’m kinda struggling on figuring out what to do next though. At the tv station that I work at my school, the cameras aren’t the greatest and it sort of limits the quality and what I can film. It’s a jvc pro hd camera but my boss basically lets me do whatever hand held not tripod like everyone else and get interesting shots, on the court when games not playing etc.

I also don’t have a computer that I can use to edit or anything. The only computer in my house is like a family computer that’s a mac and it’s not even new enough to run da vinci resolve. I literally edit all of the clips on my phone because I have nothing else to use. I’m lower middle class so it’s difficult to be able to get the camera gear or anything. I haven’t used other cameras so I don’t know how either.

I make some money when I work but it’s limited hours because I’m so young and only minimum wage in NJ so 15 dollars an hour.

And the camera that I use at work is for solely there and I can’t like bring it anywhere else. And my boss offered after I showed him the highlights I made already to let me use Sd card in the camera and bring all the footage with better quality to edit at home but the mac I have can’t even handle to store all of it.
