I took it as her saying that non-MR events were "amateur" by the way they were run, the production value, brackets and live scoring, etc.
Look at the final of the 2015 World 9 Ball compared to the 2022 World 9 Ball. By comparison, 2015 looks like an amateur event. It's all relative.
In WPA records America has never won a Straight Pool Championship.
Relative in many ways, by discipline and even year.
