Farmers who have chickens for eggs especially on a large scale, easily get tired of eating the eggs from their chickens or even eggs in general. Caterers get tired of eating their own pastries, just as people who are exposed to certain produce get tired of them due to over exposure. Do you think this experience is the same for casino owners and owners of sports betting platforms?
Do you think that the owners of casinos and sports betting platforms, gamble as much as other people do? If they gamble, do you think they gamble on their platform?
Experience is very important for the success of every business. To own a gambling platform one must have a deep understanding of the gambling business. Which means they should be experienced gamblers. There are also possibilities that they might learn the business theoretically and not practically. But the most successful gambling platform owners will have gambling experience.
For the question of if they gamble as much as others, I have not seen any gambling operator that don't gamble but I can't verify how often they gamble. Even if they gamble on other platforms, I think they usually do it secretly because this action might discourage their customers.
