I don't know the certainty of this but most likely I don't think so.
The conditions are like you said about the other disclosures and in the country I live in now there is a very big cigarette factory but the owner even hates cigarettes.
Things like this can still happen for gambling. They do business in gambling does not mean they have to plunge into gambling and do gambling all day long. Moreover, they know that gambling is not something that can be profitable for businessmen like them because regardless of anything they are managers and the ones who get the most profit for what they do gambling again for reasons of fun they are not gambling anymore I think.
I agree that business owners may or may not have a personal connection to the products or services they provide. It is essential to emphasize, however, that their ultimate objective is still to make a profit, and they may discover ways to do so within the constraints of their principles and beliefs.
In the case of the cigarette factory owner who dislikes cigarettes, they may view them as a necessary evil for their business. The same might arguably be said for enterprises tied to gambling. Regardless, it is essential that business owners make ethical and responsible decisions that line with their values, and that consumers support those who do.
It is also essential to evaluate the business's effect on the larger community. Even if the proprietor does not engage in gambling, the enterprise can have harmful impacts on people and society as a whole. Each of us is responsible for considering the repercussions of the businesses we support and making educated decisions.
