It’s not too late. If there is no problem with the pitch, you will learn it a little faster than others, just a little bit.
If you don’t know how to vibrato, you need to practice and make sure your breath control is good. If you can't hit the high notes, it's a matter of practice.
If you can’t get up, your treble pitch won’t be good, but that doesn’t matter, because it’s all acquired through practice.
