I agree! The additional tools are only for a good analyst, who already knows what he is doing (mostly), there will never be a 100% on any bet, however, it's always viable and possible to work a little bit harder to get a better understanding of the odds that are against you or on your side.
Some people always think that they have total control over what will happen in the game that they predict with total confidence and assurance.
They always stake a high amount of money in the belief that they will get a higher profit out of it, as if they are the ones who control the activity of whatever game option they play, which is one thing that always makes people spend more than they can afford to lose in gambling.
