Am not sure what does you mean about you put all into it, did you refer to how long you invest to learn Bitcoin or you're used all of your money which is $450 to buy Bitcoin? As long as you can afford to lose all of your $450 and you don't need to use that money to buy stuff in your school, you're good to go.
Not sure as well what he truly meant about it because the OP doesn't stated that he's just pouring what he can afford to lose and not all his usable funds as he stated that he's still a sophomore in high school, what the OP has said is that "
