It’s a combination of both - your tour guide, before the tour starts, will ask what specific WB shows/movies everyone in your group is interested in, and will try their best to point out and visit places that the shows mentioned were filmed at.
It also just depends on your tour guide, and what is being used on the lot for filming on the day of the tour.
The two times that I have gone have been completely different experiences.
They film at many different places around LA; Valley Village, Ontario and Antelope Valley are just a few that I can think of off the top of my head that they have at one time or another filmed at.
They film frequently in Pasadena and South Pasadena, and random places in LA that they usually only shoot once at, because the location is usually only needed for a specific scene, and is not recurring.
