It is because of this that even if casinos did not gave themselves a house edge and all their games were fair they will still beat most gamblers over the long term.
Don't thnk that way as it will not happen ,we can be chasing in gambling but a casino not using their house edge, that's running a business without assurance they'll make profit. Mind you, casino is business, yes there's a risk of losing too but they take a calculated risk and with that the house edge is significantly considered so they'll conitnue to stay profitable.
