When we talk about success, it should be viewed as a long-term process. Some of us may not see ourselves betting long-term, which makes it hard for them to relate to this concept. If someone is just betting for fun, they likely won’t be well-versed in the terminology of sports betting, as their interest is quite limited. In contrast, those who genuinely want to win will study the sports betting market and seek ways to succeed, even if the chances are slim.
Well its like you are betting on underdogs, So provably its possible and it really happens. Its just you know how to take the risk towards this since by it means that lots of people like to bet on that team they believe that this is strong team and possible that there's huge chance for them to win compare to their opponent.
But somehow for those people who want to take the risk its a "high risk,high reward" for them.
We also need to see that game to know if there's a chance for us to win even if we bet on underdog since if we just bet randomly without knowing that there's lacking players which give them more disadvantage then provably that we will end up a total loser with that choices.
