Sometimes a bettor repeats an initial mistake and consistently does so, leading to excessive losses. They believe too much in their assumptions. What I mean is, when a bettor consistently bets at odds higher than @3, it carries a high risk. Although winning can yield a decent profit, the chances of winning are slim. However, if a bettor is willing to learn from their mistakes and choose a lower risk, betting at lower odds (although not guaranteed), at least the chances of winning are greater than with higher odds. So, sometimes a bettor simply sticks to their initial plan without considering the overall loss. Without realizing it, they are psychologically attacked and have the ambition to continue betting blindly.
