Joining a band will make you better as a saxophone player.  It gets you experience playing in front of people and with the other people in the group.

Scope around for different places that you can play- could be a community college band, jam session, or just talking to people and finding other musicians.

If you’re not as good as the other people in the group….. that’s good!  It means you can learn from them.  Just keep a humble attitude and try and improve and it will make it more fun for them to play with you.

Try out different styles too, if it doesn’t work out, you’ll still make some connections and hopefuly have some fun.

Sax players are used a lot in blues, jazz.  Sometimes in classical, R&B, reggae, salsa, and many other styles.
