IME, music students to a large degree planned for their solo careers without considering enough that only a few of them would make it, and most of them would end up like teachers or, if they were lucky, as orchestra musicians.
The realism that is shown in threads like these may seem a trifle void of hope or trust in oneself, but OTOH does protect people from failing miserably.
Still, I'd say: go for it. Work your ass off doing what you love, but also make sure that you're realistic in your expectations, and know what you can accept as alternative ways of surviving.
best,
