This is due to the fact that we won't be able to analyze all the games carefully that are in our ticket and won't have the advantage needed to win. So instead, it's recommended that we should value quality over quantity if we want to succeed in sports betting.
Yes, I agree with what you said here. We tend to overanalyze when we bet too much, and with that, we tend to lose if we are not sure about our bet. Also, I just want to add that if we bet too much, then we tend to bet too much money as well. What if those bets lose at the same time? Then you lost a lot of money. So I think betting on fewer picks is much better.
Also, single betting is much better than parlay betting because in a single bet, the chances are 50/50, 50% of winning and 50% of losing. So for me, it is much more advisable to bet fewer single bets. If you can bet one single bet per day, then it is much better because if you win, which is good, but if not, then it is fine because you just bet once a day.
Placing too many bets is not good, apart from reducing the chances of winning, the level of difficulty also varies because we also need to analyze one by one the teams we are betting on. Indeed, the more we choose, the bigger the profit we can get if we can win all the bets, even if we lose 1 it can ruin everything and indeed choosing a lot of bets makes it even more difficult to win, so it's better to choose a few bets that we really believe will win so that you can get the chance to win easily.
In fact, single bets and parlay bets have different levels of profit and most gamblers choose parlay bets because the profit percentage is greater than single bets, while single bets only get small profits so if you think single bets are better then do it. But for other gamblers it is better for those who choose parlay bets not to be too excessive in their choice so as not to reduce their chances of winning because sometimes someone who is too excessive always loses their bet because they have too high expectations if their bet can win.
