There's a news going round this days that the reason why gamblers are no longer winning games when it comes to sport betting is because sport bet companies and other influential people in the world always buy matches and tell them what they should play, for example two football clubs are playing a match tomorrow and a lot of people have predicted on that particular match and if majority of gambler's have predicted on it that sport bet companies will decide to buy the match in other for those clubs to play the unexpected.
This is not true because such act is highly prohibited by nations they have a very strict laws against match fixing and any Player, coache, or official caught engaging in this practice risk being ban from the sport there by tarnishing their careers and reputations.
One of the reasons why match fixing is not supported is because it kills the passion for that particular sport and Match-fixing involves manipulation and deception, betraying the trust of fans, players, and stakeholders who expect the sport to be genuine, that news flying around about match fixing is false, if your prediction didn't go as predicted those not mean the match was fixed.
The same way gamblers lose money sometimes that's same way sport betting companies lose money sometimes, and same way gamblers win sometimes that's same way sport betting companies win sometimes.
in the top leagues where top clubs play, the probability of a fixed match is very low, but in leagues of the second tier, this can happen without problems and not only in football, but hockey, volleyball, and so on, often, ironically, the sponsors of these clubs are bookmakers (is that a coincidence?) in addition to the teams that have agreed among themselves, there are also judges who adjust the result in their favor, so in this aspect there are two negative components.
