In my view this is a somewhat nuclear version of extremely sensible advice.
I'd say your passion and core skill is rapping; producing pro-sounding records is a core skill in itself so be wary of finding all your time taken up with fun geekery of playing with synths and DAWs etc. Focus on your rapping skills, and a big part of this can be recording your stuff into a DAW over basic beats, then building a library of raps you can listen to anytime and play to your friends. Over time you'll realise the raps that remains sounding great to you, and the ones that get your friends feet tapping or commenting on / remembering your lyrics more, this will often give you big clues as to what you're really great at and what is working less.
Esp. at 15, it's great to get a relatively cheap daw and mic, and to let the thrill of hearing your stuff coming out of speakers help you hone your rapping skills.
Dont go getting into lengthily discussions on gearslutz about mics and cables until you're at least 17!
