A lot of people get pulled toward hacking content first because it feels more exciting than operating systems, wireless, routing, access control, or tickets. The issue is that offensive or advanced security material gets much harder when you do not yet understand normal system behavior, account management, networks, segmentation, and troubleshooting.
That is why jumping straight into advanced content often produces shaky understanding. You end up memorizing attack names and tools without a strong feel for the systems, users, and network patterns they affect.
