Instead of saying that maths says that the game is unbeatable, one should say that no known math has so far worked to effectively and conclusively beat the game. House edge is there in blackjack too. That was conclusively beaten with card counting by Thorpe and everybody accepts that. Similarly, through bias analysis and advantage play people like Pelayo, Eudeamonic Pie did it. Some recent university level researches prove some sort of cloaking wheel and ball does help to determine where to bet with success. House edge wasn't different for them, yet they turned them down and won.
And if someone is smart enough to know that it can not be beaten and loss is inevitable, why the hell he is a member of a gambling community like this?
Maths forks fully whenever any single outcome is equally probable and coincident to the expected probability values per each spin or hand.
Nobody can say for sure that those statements are fulfilled per each spin or per every hand.
Casinos analyze the randomness of their games by chi square tests or sd analysis made on large samples.
Nevertheless even when statistical findings are in line with the expected but they are losing consistent money, they start to investigate further.
When they don't find a reason why a game produces continuous losses, they simply remove that particular game or even bar the few players suspected to be winners.
Since there is no reason to ban people betting good money on huge mathematical disadvantaged games, we can infer that not everytime mathematics works. Even in the long run.
On the other end, why winning players should divulge precisely their strategies?
Thorp had a reason to do that as he made a lot of money selling his book.
Pelayo's family hadn't, because they accumulated millions by taking advantage of things they couldn't publicly explain.
After all players are st.upids. They can get an astounding 7% edge on EZ F-7 baccarat bets but almost nobody cares, preferring to develop strategies that cannot work in the past, now and in the future.
If I'd say that a specific generator could lead to an edge of 12% every 40 spins on average, nobody would listen to me. Betting one time over 40 hands? No party.
