Just because a team can play well, there is no guarantee that they will always win. If a gambler blindly places a bet on a good team without any analysis, he is bound to lose the gamble. So of course in sports betting or any other sector of gambling, one must first analyze well before placing the bet, otherwise there will be a high risk and the possibility of losing if you panic and place the bet. Most of the gamblers suffer because of this and lose gambling because they do not analyze well and gamble in panic.
Yes, there is no guarantee that the team will always win because of the surprise factor in the match. Often we meet a team that is not the favorite that can turn things around and even suppress a strong team so that they can win in the result. That is why we must analyze to find other information that can be useful in making a decision. This is to reduce the risk of defeat even though it will still be there with or without us analyzing it, so we have to know how much money we can place to bet. By doing so, we can avoid big losses if we lose.
