I would like to have people write on my blog and i am ok with editing their own posts while on draft. However, once their posts are published, I wouldn’t like them to be able to edit/delete any published posts, not even the owned that they have written.
Is there a way to do that ?

Add this code to your functions.php file or just use Snippet plugins to add it to your WP site. If you don’t know about how to use this kind of code just search a bit.
