I know you are a believer but let me add this ...

Clubs properly fit with progressive yardage gaps between each club will increase the probability of shooting low rounds. On 9 holes using just a single club [7-iron] my son has shot a '39'. Now with 13 more clubs he has shot '30' on several occasions. Even club pro's can shoot a low number but can they do it all the time?

A great set that performs for the golfer or pro will increase their probability of having a ton more birdie or par opportunities. Given enough games even a hacker can put together 1 decent round with ill fitted equipment, but s/he can't do it on a regular basis.
