Did she make predictions this specific? I couldn't hear everything that was said in the clip, but I don't remember her saying anything this specific.
My sense is that the different reaction would be because of the narration, not the identity of the player (though it would also make sense that a player with a decade(s) long reputation would be given more deference than a newer player).
I think the reality is she just made a shitty decision in the moment that happened to play out well. Anyone who's played poker long enough has done the same dozens of times.
