it is great that you have this goal, and I hope you will get a lot of good advice here.
You do not need a degree but you need the knowledge and the credentials. I assume that you have been participating in those activities that you are listing. Do you have a certification in any (or all) of them? If not, that’s where I would start. You will not be able to obtain professional liability insurance without it, and that is absolutely mandatory for having a studio.
Opening a studio is easy, being successful is not unless you have done a lot of groundwork. You need to consider location, competition and the market you are targeting. You will need to have a few additional instructors, and those are also not that easy to find, particularly for the times that you may want them.
We had questions like this on this forum before, and here is a link to a conversation that took place a little while back
I wish you good luck.
