You don't gain any bonus for winning/losing even if you add bets to yourself using gems.
Fleur probably felt he couldn't win it anyway, and got a bad chip (Diamond, Ruby), so let Blayd have this one, so Fleur can get the next.
At Fleur and Blayd's level, tickets don't matter anymore. If they wanted a hero maxxed out in stars, they use gems.
They win for glory and the chips.
