So "Home Made" is two people just fucking around one time and filming it.

Amateurs are people who love porn and make it a hobby. They do it all the time because they love it or hope to maybe make some money off it.

A professional is some who is paid to do it. Not just a possibility to get paid, or was paid once. Like makes an income from it, and is paid/agreed to be paid prior to the act.
