They don’t need to be mutually exclusive.

They aren’t exclusive, but they aren’t the same thing, so there’s no real confirmation that a pornstar knows more than your average woman on, enjoyable sex rather than looking like she enjoys it.

Concept of Pornstars teaching satisfying sex is to me on par with WWE wrestlers teaching self defense classes. Sure some WWE wrestlers probably have actual training in that category. But there’s probably more people with just a focus on actual self defense fighting that could do the job better.
