A point that was not mentioned in the article is that depending on the sport, there is a gold medal match and a bronze medal match. Both the gold and bronze medalist won that match. The silver medalist lost. Of course the bronze medalist lost previous to that to get there in the first place, but shares with the gold medalist a final victory.

> Altogether, they found that thirteen of the fourteen gold medal winners smiled immediately after they completed their winning match, while eighteen of the twenty-six bronze medalists smiled. However, none of the silver medalists smiled immediately after their match ended.

What did the off podium finishers look like? I am not surprised that the winner looks happier immediately after a match ends than the loser.
