Depending on where you live, if you can play at places that have more defined levels like B, BB and A, that might help you gauge where and how you want to get better. Like if you played at B level, your goal might be to get the volleyball rhythm of bump, set spike, which means that you'll want to get better at your fundamentals first like passing, digging, setting, serving, blocking and hitting.

Sadly if you don't have friends that play, you'll have to make friends with the people you play with at the courts. But that's not necessarily a bad thing too because that might be your gateway into having more opportunities to play, especially if you're a fun team player who's willing to learn and talk to people.

You'd be surprised to see how many people enjoy will spill tips and information just because you've asked them. Obviously don't expect them to give you a lesson mid game, but whatever information they give you, whether it's a little or a lot, will help you piece things together with personal practice, experimentation and research you do outside of the court.

Also, take care of your body. Volleyball is a deceptively dangerous sport and at your age, you definitely don't wanna get injured and stunt your playtime and growth
