I think the lyrics are very meaningful. Have you ever played Roulette? It can be bloody addictive and many good people have come to ruin gambling in games such as Roulette. "Caught up in a game you can't win." That's really true. You can obviously win, but if you don't know when to walk away then you're never gonna be a winner. I think you should listen a little more carefully and perhaps play a little Roulette if you wanna understand more.
