Well, why did it only scan 3000 pages out of 5033? It decided it didn't need to? It took a sample and decided it was gonna be okay?

I don't know. Hopefully others with more knowledge can answer.

I think it could be because the pages did not need to be looked at.
Perhaps the database tracks whether a page has deleted information and those are the ones that vacuum looks into.
