The chances of you making it as a "pro" bassist are immensely small. They are not zero, but they are small. Do not neglect education, that should be your number one focus because you don't get a do-over on that. One time through high school to get a grade and record that will determine your entrance to colleges and one shot at college that will determine a trajectory in the professional world.
My advice, don't be a pro bass player. Write songs, do vocals, play keys and guitar and then play bass. Then you can be in charge of your future. With just bass, you're dependent on being in the right place at the right time to ride along with a successful band. If you're not getting song writing credits, you're just a guy along for the tour.
