It’s pretty clear to me given the cops shooting, then shouting orders, and Mr. Pink saying he’s been shot, that he does not in fact get away.

I know there’s theories on the Internet about this, and he may not have died, but at the very least he’s been caught and does not keep the diamonds.

None of the thieves got away at the end of Reservoir Dogs.

This is not to say that “good” triumphed at the end either.
