I do not think that using math or other predictions you can win in gambling, and especially in roulette. There everything is designed for pleasure, not profit.
Precisely, for me I also don't think that math could help you to win in gambling maybe sometimes there is a chance but it is only a little. As far as I know in order to win in gambling you must have a high amount of luck and even though you have it you still lose. Besides, gambling is not worth to gain profit.
