During the PF1 days tha rulebook line was all considered "core". That changed in 2E, and the Paizo staff has said over and over that Core for PF2 was CRB, GMG, APG, and the Bestiaries. This is why books like Secrets of Magic and Guns & Gears got different spine treatments. The core line has the matching spines, the other rulebooks have unique spines.
It also depended on the context you were discussing - for Pathfinder Society, the PF1 Core campaign is only the core rulebook. People have been using these terms with differing meanings for a long time now!
