I think if you are not lucky in life, then mathematics will not help when you came and lost all the money.

Mathematics is different from mathematics ... There are people working out such grandiose schemes of earning money in casinos that whole books are dedicated to them or films are made.
But these are only units that could work out this way, give another person such a scheme, then nothing will come out, he will not even understand how it works.
sometimes there are cases of luck when a beginner who does not understand anything in the game can get a very big win.
