From my personal experience, it seems gambling is designed this way, and it is a true test of our emotions. When you want to be serious, you will lose more but when you are unserious, the winnings will surprise you.
I have had this experience many times and I end up feeling bad because the games you don't expect to work are those that will eventually work as predicted. Assuming a gambler can adjust to this casual pattern and make it a habit, I'm sure the result will be better than this serious forecast that always turn out very disastrous.
This is the reason why I do say thst gambling is mostly luck based and anything asides that will definitely not be gambling, because in gambling you are only predicting the possible outcome and not you been sure of the possible outcome, and that's why you don't have to be serious or not you. Win a bet, sometimes you win a bet regardless of the efforts as the casinos isn't a rewarder of effort but luck, although your skill and knowledge about a particular game can come in to help you increase your chances of winning but it's not a guarantee you will win.
Don't gamble putting all your hope on it, gambling casually helps you gamble with less emotions and so you could just win without stressing because you did gambled with a mind of accepting whatever it is rhe out come will be and little or no emotions were attached to it.
In my opinion, gambling games such as poker and sports betting are the types of games in which you don't rely on luck, if you want to test this today you can, today we will have 2 games from the European Champions League, they will have the following games:
Manchester City FC - FC Copenhagen
Real Madrid - RB Leipzig
You can test without analyzing these 4 teams and bet that there will be 6 goals in both games, that is, in the Manchester City game against Copenhagen you bet that there will be 6 goals, for that you just have to go to the over market and bet on over 4.5 which has an odds of @3.35, if you bet $10 you will win $33, then go to the Real Madrid game against Leipzig and also go to the over market and bet on over 4.5 and by betting $10 you will win $45 $ and you count on luck, after the game ends you see if it was really worth counting on luck or if it would have been better to analyze each team to see if they could score a lot of goals or not and what would be the best market to bet on
In this case, probably if you analyzed each team you could come to the conclusion that betting on Manchester City to win and Real Madrid to win would be the best option and as the odds are low, placing a multibet bet with Real Madrid and Manchester City to win with odds of 1.7 would be a good option, by betting $10 you would win $17 and if you put other teams in that multibet bet, if you won you could get a high profit and without counting on luck, you will be counting on your skills, if you lose it just means you weren't very skilled , it has nothing to do with bad luck
