The number of people who see Tom Scott's channel and suggest he wouldn't have a million subscribers if he wasn't as handsome is close enough to zero to be negligible. People believe that his success comes from his content rather than what he looks like.

It's perfectly reasonable to assume the same is true for channels hosted by women. We could be wrong, just as we could be wrong about Tom's subscribers, but everyone's better off for it so maybe being wrong is fine.

I can talk about Simone's work without adding a caveat of "...for a pretty woman" to explain why her ingenuity and humor is successful. I might be wrong, but I think it's worth it.
