I have seen most people who pay money for the bet just because someone informed them about the game, I will be like... Wow, why will you bet on a game you have no knowledge about and funny enough they will end up not winning the game. People intend to stake more games and analysising multiple games at the same time is stressful so you might not have an assurance about the game also. Even with the idea gambling is said to be a lucky game so staking multiple games can still give you more chance of winning under probability, I just focus on the money spent and I make sure I will not gamble and forget my limit
The thing is, most people believe there are people who are so good in terms of prediction, and just because those set of people have been able to make some good and perfect predictions about some certain games and the games play as they predicted, people now worship their predicted games and will be willing to do anything just to have that game played.
So these people set up some prediction group where you need to pay to join the premium group and enjoy their games, but gambling is always gambling; their predictions won't always come out right all the time; sometimes they play, sometimes some of the games lose, so those who pay to get such games are doing that at their own risk.
