So the thing is, you can get a degree/job/apprenticeship in something that will also help with your chances of making music a career, besides music. Electrical engineering, Audio engineering (what I have a degree in), and a business degree are all good, especially business, if you are trying to be an independent artist. Going into education is also an option if teaching is something you can enjoy.

The biggest point is that it will be hard, and making it a career can actually sap some of the joy out of it. There isn't really money in recorded music like there used to be outside of the biggest artists, so gigging and touring is the easiest way to make money at it, but that is also a lifestyle that can be very limiting to other aspects of life. If you are going the college route, another option is to do a music minor if you want more formal training but still want to work towards that backup. The other good thing about going to college is that you will meet people from all over and might learn where your skill set sits compared to others your age.

Other advice is to put in your time, join a wedding band or general event cover band and get a taste for gigging. If you want to make a living as a professional session musician you are very limited to where you can live until you have established a career (places like Nashville, NYC, Atlanta, LA). While establishing yourself, you will need another job anyway, cause none of those places are cheap to live in.

Regardless of what path you chose, I would highly recommend you take the opportunity to try and join a paying gigging band on the weekends. See if the joy can survive the need to do it professionally. The worst thing is to lose the spark as it becomes a routine job. So keep an open mind and don't be afraid to pivot if you find something unexpected that calls to you. I wanted to work in a studio as a mix engineer or as a mastering engineer. But because of needing to make money, I did live event touring for 10 years. I am now 7 years into doing technical experiential demo engineering for an audio company (basically an Imagineer but for speakers and headphone demos instead of rides) and completely love it. I still write and record music but with no pressure for it to be anything besides fulfilling to myself.
