I think the only ones who can make money are those playing poker and are really good at it. That's because they are playing against other players and not the bank. They still have to beat the rake.
I'm not even sure comp players, that is those who play to get non-cash rewards like travels, restaurant and hotel stays while minimizing their losses can still have an advantage. I heard that casinos calculate comps by expected losses, making sure they stay on top (statistically).
And they are cheaters, but it is like saying thieves can make money.
Absolutely not. Using your brains to keep track of cards is not cheating in any way, shape or form. They are simply using all the available information and some pretty basic math to them to gain an advantage.
Calling card counters cheaters is like calling chess players with better knowledge of patterns than their opponents cheaters. They are not cheaters.
The cheating it mentions at the bottom is not card counting (technically legal), but genuine cheating.
