It is a bit dated but according to a 2005 National Golf Foundation [NGF] report the distribution of scores among men is as follows:
< 80: 5.0% of golfers
80-89: 19.7%
90-99: 27.2%
100-119: 32.8%
> 119: 15.3%

And the average score of amateur men is 98.3.

In other words, Golf is hard and we need to temper our expectations. For as much as we think we should be able to break 90 (for example) only about a fourth of all golfers do it.
