Are BR games an "E-Sport"?

I believe it is an e-sport as it requires skill and more gamesense. I don't like repetitive games. I'd like games that can change all the time requiring more skill and you need to expect the unexpected. CS:GO (as an example) only has 6 categories of guns and are always at the same spot. Which only required around a day to learn the map but with games such as fortnite it can be 1000s of games until you fully learn everything.
