It’s a no loss situation; this means absence of any competing or non-competing losers. It’s like tee ball with no score and where every kid gets pizza, a snow cone, and the same “League Champs” trophy.
This is different from the clichéd "win-win" situation. If there are winners then there is at least 1 loser.
No loss is far better than win-win. Plus it's cliché worthy.
