selling same photo elsewhere?

First, let me say I'm just doing this for the first time.

I did read the online info about selling my photo's on Adobe Stock.

What I'm not clear on is if I can sell the exact same photo elsewhere?  Not just on other stock photo websites but also on Etsy, my own website, and Fine Art America?

I don't want to break the rules and get booted off!

Thank you for the help!
