To be very honest, there is no method or technique in the world which will get you 100% guaranteed win.
As we are talking about sports betting, which is another way of spending your money on somebody else's luck.
Definitely, in gambling, you don't really know the percentage of winning, the system seems to be always in favor of the house, but in terms of sports betting, teams are likely having a very small difference in their skills. But I can think of one thing to be success in sports betting but it is unlikely to be applied by the gamblers. If we are going to participate in the game itself and we will do our best to win, we can bet to ourselves before the game starts. In this way, we have the outcome in our hands.
So, I am sure this is just another spam post to attract attention and nothing else.
I will advice everyone to stay away from such beliefs and sayings.
Perhaps, he has a point, but the chances of this to be effective is quite low.
