Free wordpress themes at monthly events, What can I do with those free resources?

I’d like to know what can do with these free templates. I’m a newcomer and want to know if I can sell a website with these templates, in addition, what is the duration of these regular licenses that get me?

between more examples better, Thank you.

It’s the same as a regular license Regular License | ThemeForest except that you do not get access to the same support or updates that you do when buying an item normally.

So for example, yes, you could sell ONE website for ONE client, but remember you will need to write any updates or bug fixes for yourself without author support
