~ Luck in gambling is an entity independent of other factors. Luck just exists. Some people are lucky in gambling. They win big sums of money. That is what fascinates people. Single combat with fate (luck).
I agree, only it's not like some people can be inherently luckier in gambling than others. We can never say in advance who's more lucky. Only later, after someone won a big amount we say, "Oh, he's a lucky bastard!" Only post factum. And nothing, absolutely nothing, including Feng shui, can change that.
