If I remember correctly that is from when the Bruce Willis character was telling a story about a fixed horse race that was thought to be a sure thing. But word got out because of how gamblers are -talkative- and then the race wasn't such a sure thing.
So my take would be that the line was referring either to folks who had inside information but couldn't keep their mouth shut or on the other hand, degenerate gamblers that were constantly pestering bookies or other people for information.
"When the snows fall and the white winds blow, the lone wolf dies but the pack survives." Winter is Coming Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die. As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
