When I place sports bets, I like to study the statistics of previous games, check the lineup, and consider the importance of the match. If I’m unsure about the odds, I’ll most likely avoid betting. Only if I want to watch the game and make it more exciting, I might place a small bet. I rarely go for pure luck, and usually, I don’t win that way.
Football is not even something someone will place a bet on without knowing what you are doing and wanting to depend on luck alone. Anyone who wants to depend on luck will go for luck-only-based games, which are only found in slots, random picking for football matches, and making your guess, which will most likely lead to losing. It's better you know what you are doing even if you are unsure of your prediction than going in blindly.
You're right. Don't place bets on the basis of luck when you do not understand the gameplay. It will be like working on gullibility. You don't bet on what you're ignorant about. For football games, you study clubs based on their performances in the current or previous seasons, you study the strength of the squad depths and the new transfers of players or manager they've brought on board then compare and contrast with the opponent's performance, strategy and squad depths before taking your final decision in playing your bets and how many odds you are sure to have on the games.
Always avoid using emotions and overconfidence when staking your money and placing your bets because you might end up in a deeper mess when your sought after club or fails to the other side.
