Stupid question: am I on a stable release? Or how do I get it?

I realized this is a pretty stupid question, but this is a community full of people who have much more experience with the beta program that I do, so hoping to get some help (probably should have done some more homework before joining).

Basically, I'm trying to opt out of the beta program without wiping my phone. I'm on build number BP31.250523.010 with the June 5th security update and the June 1st play update. I did a bit of research and I think(??) I should be okay but wanted to check here first.

Any help and guidance is appreciated!! Thanks so much!
