It reminds me of writing an objective examination in high school and when you're done with the questions you're certain of, and you just do some random selections and luck could shine on you and you get up to 70% from your rough prediction.
I have not tried this in real games that involves using money but would want to know if anyone has ever tried it before.
Have you ever placed a bet by just doing random guesses on the outcome of the game?
Well, your luck does work out sometimes even in sports betting, but in general, you can't depend on luck all the time because you can't get all the guesses right all the time and you will start losing more bets as you continue. If you had tried the same thing the next day, you would see different results for sure, but if you were making bets after knowing the sides and understanding which player or team has a higher chance of winning, you would have a higher winning average.
So sports betting is definitely different than gambling games because gambling games require no knowledge or experience for you to win, but when it comes to sports betting, you can only stay profitable in the long run if you have enough knowledge about the sport you are making your bets on.
