all strategy are the same whether it is based on mathematics or not , those are still not guarantee to work because a gambling is purely based on luck and not on skills , strategy , emotions , or whatsoever . theres no difference of playing poker and other casino based games but what matter the most is your luck . if your lucky you can won but if not then you can go home empty handed .
There is huge difference between poker and other casino games. In poker, you play with other player who has exact the same probability of winning. If you both have the same probability than strategy and experience is a factor that will give you advantage over other player in a dozen plays.
You may have bed luck 100 times in a row but with experience, strategy and math you will count that you have low probability of winning and you will pass loosing only first bet in auction. Than with one lucky set you will take back all your loss.
Poker is more like trading on stocks/forex rather than gambling. You never know everything but you can count probability and do money management.
