Depends how closely matched people are. Last few times I've played games with friends/family who aren't poker players, I literally took all the money and I'm just using poker 101 strategy. The skill is all in getting people to play with you more than once :(

And if you ever watch casino games -- it's just a constant money spigot from fish to sharks.
