For someone who is 18 and very creative, the facts you posted could be helpful to say that they have a chance to be insane lucky if they have the aprox 1 in a billion set of skills and timing required to make it to market.
On the other hand, the stats in the article point out that for someone in their 30s or 40s, they have 1/(10? 50?) chance to be able to found a successful startup, for some definition of the word startup. This in general seems a much more useful message to push.
A similar story is around education. Some of the richest people in the world did not attend college. However, for 99.9999% of the people - going to to college and getting a science or other hard degree is going to lead to a much nicer life then to go straight from high school to the working world.
Cool to look at the 1 in a billion case, it is not always as useful for a case study.
