As I understand when a user with low privilege does some actions only available for users with high privilege this is called privilege escalation.

And authorization bypass is when I do some actions which I don't have the permissions to do, if I'm not mistaken.

What is the difference?

These terms focus on different aspects of the attack: privilege escalation describes what was achieved, i.e. gaining higher privileges, no matter how. Authorization bypass describes how things were done, i.e. by bypassing the authorization, no matter what was gained this way.
