For many years people have had a bad perception of the gambling industry because they think that the betting options they present are fixed and that it will be impossible to win. In other words, most people think that the house always wins.
The reality is that this is a half-truth; most casinos in Las Vegas strategically prepare their games so that the house has the advantage, but having the advantage does not mean that they will always win.
In the case of bookies that are associated with a reliable pay per head provider, they have a team of experts who prepare the lines and betting options trying to guarantee the highest profitability for the bookie.
In both cases with the casinos and the bookies, are simply trying to improve their chances of winning, but there is always the possibility that the gamblers win, which is fine and in fact, should happen quite often, if they want the business grows.
When players win they get excited and in most cases continue to bet, even increasing the amount of money they bet, as they feel confident about the good luck run. Eventually, the player will probably lose much more money than the one he won, so the bookie recovers his money quickly and with profits.
On the other hand, if you have a betting site where no player ever wins, it is most likely that you are out of business in a couple of months. Since the players are going to be frustrated with your betting site in a short time and will look for other options.
The bookies do not have to be scared to see players who win inside their betting site, on the contrary, they should be pleased that the betting site is working well. Nevertheless, they must be very careful and monitor the reports of bets from their betting site, because if they detect a player with a very good or very long winning streak, there is a possibility that he is cheating and actions must be taken to avoid losing money because of a cheating player.
