As I understand it, the PGA stats (
https://www.pgatour.com/stats/stat.109.html) are for money won in tour events. In a typical week approx. 156 start, approx. 80 make the cut and they are the only ones paid, based on their finishing position.
(1) Not all PGA members get to play an event. Only those with the highest rankings are accepted.
(2) Friday afternoon approx. 76 "slam the trunk" of their car and head off to the next event hoping to get a start and make the cut.
These are the current elite. There are lower ranked tours (even in the US) where the prise money is significantly less. The big prize on a lesser tour is the top (say) 10 automtically get promoted to the bigger tour, but they are ranked behind the top 125 from last season so there are a restricted number of spots each week (156 - 125, sort of). Sort of, because the next week's sponsor reserves spots for players they want to see.
So there can be a bit of pressure on Friday to (1) play and earn in the weekend; and (2) on Sunday to maximise an earnings opportunity and the chance to play next week.
How good are you from 40 meters out on a slight angle knowing you won't get paid this week if you miss?
