Yes it's all about the player style, not always win but not lose big amount.
How? I don't see any strategy in gambling works. I haven't seen anyone who did it and consistently win in any game. All in gambling is dependent on luck and not on strategy, there is no perfect timing nor right amount of bet that could make you win consistently. It's sad to see people who are betting and believes that they might be at the right time and with right bet. There's no such thing as like that in luck based games.
I agree, on luck based games you must have a greater amount of luck on you than your strategy. No matter what strategy you use as long as you have great amount of luck you could still win in that game. Because the house is your opponent any strategy can work but it will still be based on your luck if you are going to win.
