In betting, unexpected things like that can happen, and we can't fully predict it. It can be said as a luck factor in betting. However, even so, it doesn't make betting entirely based on luck, analysis is still a bigger factor in winning a bet. Therefore, in betting, we should not be too confident in the analysis that we have made before, because it could be that the analysis we made is the opposite of the reality in the field. Always understand that bankroll management is important and only bet using money that we are ready to lose.
Betting is no different from trading, because traders also analyze the deal before making a bet, study the charts, look at the upcoming news on the asset they want to buy, this is the analysis of the deal. Different games can differ, for example, slots cannot be compared with trading, because in this game everything is decided entirely by luck, and in trading I have not seen a single successful trader who would open deals simply at random, relying only on luck.
