It's not even just "pro gamers", the most popular fighting game in the world (Smash Bros U.) is enjoyed by casual players and pros, and has an entire mechanic based on "two-framing" for edge guarding.

One absolutely does not need to be a pro to pull it off, and the whole interaction window for that mechanic is based around being able to react within ~32ms (1/30th of a second) to edge guard an opponent. It is exponentially harder to pull off in online play.
