What does Ecclesiastes 9:11 mean?

I’ve seen something else under the sun: the fastest don’t always win the race, the strongest don’t always win the battle, the wise don’t always have food, the smart don’t always get rich, and the educated don’t always get favor. Time and chance happen to everyone. Ecclesiastes 9:11 - Modern Text Bible

(Success isn’t guaranteed by talent or effort. Luck and timing play a big role in everyone’s life.)
