'Skillful' in the Bible

I also realized that all [of the] toil and all [of] the skillful work that is done--it [is] envy between one man and {another}. This also [is] vanity and chasing wind!

I looked again and saw under the sun that the race [does] not [belong] to the swift, the battle [does] not [belong] to the mighty, food [does] not [belong] to the wise, wealth [does] not [belong] to the intelligent, and success [does] not [belong] to the skillful, for time and chance befalls all of them.
