Every sport you described there involves a competitiveness of some kind. A scoring of some kind where the better example is the winner. That is sport. That is why ballet isn’t a sport and synchronised swimming is. I feel like thats a bit of a strawman argument, as I never made that claim.
Wrestling is scripted, and while I again say that it takes skill and effort to do the acrobatics and physical things the people do, there is no competitive element to it outside of the acting…
If the winner of the 100m race (your example) was agreed ahead beforehand, it would also not be a sport would it?
EDIT: here is definition of sport: n - an activity involving physical exertion and skill in which an individual or team competes against another or others for entertainment.
To me the focus is on the compete. The only thing WWE wrestlers compete in is popularity… if they’re sportsmen, by a stretch so is every youtuber
