RTK is an additional unlock on most receivers. It may be capable, but not unlocked.
Do a google search on RTK and VRS. That will answer most of your questions.
The short of it is, your receiver sends its location to the VRS server (CORS network) and it creates a virtual base in your location and sends correction data to your receiver.
