Those who know how to win are much more numerous than those who know how to make proper use of their victories.
Meaning of the quote
The quote means that many people can win or be successful, but far fewer people know how to use that success in the right way. Just because someone wins or achieves something doesn't mean they understand how to truly benefit from it. The most important thing is not just winning, but using your victories wisely and effectively.
