I can't find any information on stackoverflow or google about the meaning of =$1. I get superficial information but nothing for beginners like me. What does it do?

If I have something like this:

www.website.com/profile.php?simon

Does the name simon correspond to the $1 variable and why 1?

This is how I understand it:

• (.*) profile/profile.php?id=$1

The bold corresponds to:

• www.website.com/profile.php?id=simon

Converted with rewrite it becomes:

• www.website.com/profile/simon

Am I missing something here?

Edit:
