#20: Gary Player
Next up is Gary Player, a South African professional golfer who is widely considered one of the greatest players of all time, although he is now retired. Amongst his many achievements, he is the only non-American ever to achieve a career Grand Slam—that is, to win all four majors in a career.

He did not grow up in a wealthy family; his dad had to take out a loan to buy him his first set of golf clubs. That’s not a problem that Player’s six children will ever face, as their dad has a net worth of 25 million USD and probably keeps bringing in more.
