Some people could never be professional musicians. There are millions of them trotted out on the X Factor every year. For others, they're so talented that it would be harder for them to not get noticed.

Being honest, and going purely by the info in the question (which really is not much) I'd say that it's unlikely for you.

If you want to go into pop and make millions of dollars and be loved by fans, you have a better chance of winning the lottery jackpot. — you need connection, talent, and a person to sponsor your career, all hard things to get.

If you have worked hard since you were eight on a specific instrument, and want to be a professional orchestral musician, then I would say your chances are pretty good.

if you don't have the music where you want it art-wise, you might want to go work on that, this article isn't going to help you much either. you will be better off by practicing and studying and working on your music instead. you will need to get the art pretty close to where you want it, before you should worry about making much of a living out of it.

keep your expenses very low. read that one again. move someplace cheap. drive a good used car. do all the things it takes to be a secure un-monied person. you have to have health insurance. you have to have a reliable car [unless you live in nyc or something]. you have to have some money in savings. you have to pay your taxes. don't have a big expense of alcohol or drugs or any drag on your system like that. i wouldn't even smoke. use your head. spend very little, save as much as you can and don't get into any big expenditure until you can afford it, maybe never. buy your gear used. research as much as you can. think about it really hard before you part with a dollar.

learn how to honestly add and subtract without emotion. if you spend more than you take in, you lost money. i can't tell you how many folks that i run into that have trouble with this. if you bring in more that went out guess what? you just made money.

stick to this low-overhead model, if you end up making a bunch of dough, you already know how to deal with it. if not, you still get to keep working because you don't have a bunch of stuff that you have to dust and pay for.

the more overhead you tack on, the harder it's going to be. and the easier it is to get knocked off course.

Don't be afraid to do other things to make money in the short term. this can be a very rewarding experience. historically musicians have been barbers and bartenders and all kinds of stuff to make ends meet. this is totally fine. don't worry about it. it's cool. do what you need to do. waiting tables will give you lots of stuff to write songs about. i used to call myself the king of the part time job, because i could get up out of my chair at any time and go get a job of some sort. not that it would be the greatest job of course, but i could go and get something going. i've cleaned pools, painted apartments, done maintenance work, taught music, worked in a factory, threw newspapers, drove a delivery truck, cooked, all kinds of stuff, and none of it killed me. through it all i was able to keep practicing and writing music and studying what i was doing. bills? hey no problem, go flip a few burgers and i can pay that and get back to playing the banjo. get a job in a dance band whatever i have to do. just live within your means and you can avoid so many hassles. hassles interrupt your practice routine.

I should not recommend any materialistic person to read this comment skip i don't think he /she is going to like what it says.
