Yet she's sponsored and gets free flights etc.

That's the literal definition of a pro, someone who makes money or the equivalent (shit that costs money).

But the implied meaning that comes with pro is that they're experts, since you generally have to be an expert before you make money from it, so calling her a pro would be a perversion of the word pro.

This video is private.

actually being a professional just means you get paid to do something

"A professional is a person who is paid to undertake a specialized set of tasks and to complete them for a fee."
