How to set user rights in Joomla?

Question

Joomla

Hello!
There is a task. Set user rights on the site so that the user can log in, add an article and new material, but at the same time not see the materials of other users, including media files in the library. There are a lot of users, more than 20.
Is it possible to solve this with rights settings and groups?
I would appreciate advice and experience.
