Any loss of money is always a significant or minor source of stress. I don't think that even those who have a fat wallet, realizing that at some point their money is stupidly lost, do not experience at least some grief. There is a good expression, "There is no such thing as too much money." Therefore, as beginners, we often bet on self-confidence but lack an understanding of many subtleties, which can result in losses. But we should take away only useful things every time, even from our mistakes, replenishing our experience. Sports betting requires good analysis. Even with a good understanding of the rules, there are not many winners, since sports are always full of surprises.
