Yes I've been to a PGA event. The firefighter who played in the Masters and US Open a couple years back is from my hometown. So yes.
There is a gap between low handicappers and touring pros. But it isn't as big as many think it is is all I'm saying.

Honestly, the biggest difference between touring pros and low handicappers is 1) ability to remove flag from the equation and 2) the greens.
The PGA tour plays on greens that are massive and for the most part, they can two putt from anywhere. If a touring pro removes the flag and aims 20 ft left, then misses target 30 ft more left....they're still on the green a large percentage of the time.
The greens that we all play on are barely 30 ft wide. So missing the target = missing the green = bogeys.
