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.
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.
If anything would have a guaranteed result, then everyone would just follow it and make money form that source only and would not have to do any other things. So just blindly do not follow in any such thing and better to investigate and develop owns knowledge so that we can have advantage in something over others while gambling rather than believing any such things.
