I looked out for sports I wasn't conversant with the athletes and didn't know who was better at the sports and did a random prediction on the outcome of the game. I did it for swimming competition and some random boxing yesterday and out of up to 7 predictions I made, almost 6 went the way I predicted it.
In most cases where people are starting out in sports betting, they look at the many games they are in at the betting house and choose the games in which they have a clear favorite and bet on that favorite without carefully analyzing each team or each player, and in these cases people may even have many hits, but it is not something that can be profitable in the long term because they bet on games with odds below @1.50, even if the person hits 10 games that have odds below @1.50, it is enough for that person to miss a few games to be at a loss.
Have you ever placed a bet by just doing random guesses on the outcome of the game?
Yes, I have, when I started making sports bets I didn't know how to analyze the games, so I would place bets on teams that had low odds and on teams that I like, for example I would watch the Manchester United vs Wolves game, Manchester United had odds of @1.40 while Wolves had odds of @7.00, I would run to bet on Manchester United to win, I didn't analyze the game, the worst part was when I lost a bet, I would get angry and wonder why I made a mistake, at that time I had no idea that betting randomly was bad.
