I dont think that you are right, because there is a lot of factors in this bissnes...
Just a few examples :

1) If you coming from the "wrong" country, its much much harder to start. 90% of a good programs, dont work with people from Russia, Israel and more...
So webmasters from this countries, starting to promote programs that convert realy bad...

2)Not everyone speak good English...
My English is realy suck, so it will be harder to susses.

3) Money
If you have a lot of money to invest...fine. your chansies are much better than someone who dont have the money, and need to start to work with a sponsor hosting, that bun in a lot of places...

So its just a few factors, there is much more...
I Know people, who start from 0 in first 3-4 month, and now making a good money.
3 month its not enough time.
