Not necessarily, Apple only implemented the latest and greatest USB charging spec in some of their devices (AVS). Their chargers speak the new protocols so their devices and their chargers will work, but a charger from a few years back can easily deliver 100W following the spec (PPS, other PD standards) but be unable to deliver high power charging on some Apple hardware.

Neither side is wrong per se, though it's quite annoying that Apple didn't implement PPS. Then again, if you're buying Apple, you should probably expect these kinds of shenannigans and be ready to need to buy dedicated peripherals.
