Yes, to people to whom you have distributed the binary.

No, they can also get it from someone else who has a (presumably paid-for) binary, and lawfully use that copy. Because GPLv2 s3 says "You may copy and distribute the Program ... in object code or executable form" someone who gets the software from you has the right to copy it for their friends, and because s0 says "The act of running the Program is not restricted" anyone who comes into possession of such a copy may use it. s6 makes their position even clearer: it explicitly gives them a licence from you to do so.

The GNU GPL is fine with you charging for your software; it just requires you to deliver freedom along with your binary. If what you're asking is "what licence should I use if I want to charge for my software and forbid my paying users from exercising the freedoms associated with free software", that would be off-topic for this site.
