This article doesn't state that you can win at roulette by using math, it says this at the end:
We can dress up the layout of the wheel, the layout of the betting cloth, our number selection and our money management system however we like, but the maths is always there, quietly working against us. You might as well just have fun, pick random numbers and trust to Lady Luck. Either that, or do as Einstein suggested and steal chips (not that we’d recommend it).
So no, it's not possible to win at roulette just by using math.
For other games it's possible, but keep in mind that casino's are doing everything in their power to prevent you from doing so.
I'm thinking of blackjack specifically, they have security measures in place to prevent you from counting cards. If they even suspect you're doing this, they can ban you from the casino.
For pvp games like poker, you can effectively use math to gain an edge over other players though.
I think you are pretty wrong!
After all all games of chance are pure math (that is why they say math is working against you).
There is a way to gain better odds - this does not mean you will win 100%, just using math you could turn the odds in your favor.
The problem with casinos is that they have staff that knows math way too good, and their job is to find the strategies that can turn the odds around and to figure a way to stop them.
So if you create a roulette that is pure chance where it will land and has no protection against any strategies then you can beat that one.
In the casino they have min and max limit to eliminate most of the strategies. They also have other ways to interact once you start winning and they do not know how you do it.
So in real casino it will be hard to beat it, as it pays millions of millions to people to figure out how it can be bitten and to prevent it from happening.
Good luck gambling
