Eh ... they're pro wrestlers. I think they're expected to talk a little Smackdown. Austin said almost the exact same thing about Goldberg and wcw in regards to him being happy to wrestle him if he ever leaves the Bush leagues.
Omega wasn't exactly humble when he said everyone he's competing against in the Wednesday night wars would be working under him if they were in the same promition.
There's an element of truth to all of it, but it's wrestling so you dial it up a notch because that's just how wrestlers are expected to talk.
Lord only knows what Seths girlfriend would say on social media if She were asked the same question but I can almost guarantee you it would be lacking in the humility department.
