I find it obvious from the context that they were referring to celebrity CEO:s in global corporations and not Mom or Pop in some small mom-and-pop corner store.
When I look at en.wikipedia on Huang it seems he graduated into a managing role and then founded Nvidia. By "real-world experience" I'd mean experience as a worker, but I can't answer for the person you're actually quoting.
However, it's an interesting example. Clearly Huang has managed to promote an image to you that is very different from mine. As I see it, Nvidia is a main supplier of hardware for globally fashionable grifts and scams, like large portions of so called 'crypto' and 'AI'. I also expect Nvidia to be an important supplier in the war industry, and I'm sure it is in surveillance tyranny.
