You are right, but in in his "cartel", everyone was working for him. Kind of a monarchy. I feel these cartels are more of an actual oligarchy where each player has a separate role that gives it power instead of just reporting up to Pablo.
Taking the insurance example you have the "suppliers" (doctors, drug companies and device companies), the "venue" (hospital) and the "extractor" (insurer).
Similarly you have the "suppliers" (musicians), the "venue" (the venue I guess) and the "extractor" (Live Nation and Ticketmaster). No obvious mapping to the record labels, recording studios or (biggest of all) streamers but hopefully some similarities are present.
I feel like Escobar, the Sinaloa Cartel, etc, are much more top-down.
