It is mostly celebs/influencers who are deepfaked into porn. That's where the money is. But it has also happened at schools where someone does it another student/teacher and passes it around.

I don't know if it is true that "that's where the money is" (some of the people quoted in the article are making a whole lot more money that I do at my six-figure tech job). But deepfakes of celebs or students is not what the article is about.
