My guess is that if you were betting on a race, you would put your money on the swift to win, and "sometimes fast runners trip over" wouldn't seem as smart.
The rewrite stinks of a consultant's report where humor is frowned upon, business is serious, and there's no way we could write in plain words that the CEO got there by chance. Objective consideration distances the author compared to the subjective original I have returned and [I saw]. The original gives examples, the rewrite's contemporary phenomena is vague enough to avoid calling out the board of directors. A compelled conclusion is one the author is - reluctantly, you understand - forced into. Innate capacity leaves an escape hatch for a education from a good school and life experience to excuse the board again. It's not an honest rewrite of the same sentiment - a subjective take that life isn't fair and it's not just here, and us.
A plenitude of observations undertaken in a multitude of geographically and culturally diverse locations has convinced this author of the incompleteness of the following claims: races are won by the swift, battles are won by the strong, bread is earned by wisdom, riches are earned through applied understanding, and favours return to skilled persons. Absent are the effects of time and chance on all situations, of which experience has made abundantly clear. Other phenomena may too have their inputs, e.g. underhanded manipulation.
(Swiftness is still the best available predictor of who will win a race, though, and training cardio, muscles, diet, electrolytes, mental endurance, is the best available way to increase your chances of winning and not dropping out, tripping over from tiredness, or getting cramp, even though you can't change your innate ability or age, and time and chance happeneth to ye regardless).
