You won't see that big of a gap because someones steal range is off by a couple pips or because they puss out and don't bluff the river with the bottom of their range occasionally. It likely means that one of them is routinely make stupid decisions preflop. It's not the only way to bleed money but it's far, far and away the most common.
Also - having a 100k downer as a 1bb/100 winner isn't that uncommon, but having a 100k downer as a 3bb/100 winner should be extraordinarily rare.
Just as an observation, I know there are a handful of super-good LAG's out there, but the vast, vast majority of live limit players grossly overrate their abilities to get away with playing bad hands pre-flop and make the money back post-flop. (The psychological reasons for doing this are obvious: playing tight is at best boring, and at worst frustrating, when all the other players are getting into hands against bad players and you have to sit out.) And even among the super-good LAG's, part of the skill of being a super-good LAG is actually being disciplined about it and realizing when there are times you have to tighten up.
So when you see people repeatedly show up at showdown with hands that are not borderline but are clear pre-flop folds, by far the most likely explanation is that they are a significantly losing player, even if you see them making some good post-flop plays. Since variance is a long-term process, such players can rely on rungood for a long time, but eventually, all those times they play a weak hand against a strong range come back to haunt them.
