Nobody considers the casino business as an investment.
The casino business was built using quite a lot of cash capital and the owner must continue to prepare money at any time if needed and profits from this business can be obtained at any time without having to wait for a long period of time if the casino has achieved success and managed to become a big casino while investing someone spends money to get profits and profits can be obtained when what is invested has high value and requires patience because investments tend to be long term.
Even though both are equally profitable, they have a big risk of experiencing a loss or losing the amount of money spent.
But it is true what you said that the gambling business can generate more profits than an investment.
Business is a business that was built or started from 0 with hard work and full of struggle to be able to get the business to grow big so that it can generate a certain amount of profit that is certain for the business owner, while investment is giving money to make an investment asset in order to get a profit if These assets have high value and it is still uncertain whether they will succeed because in investing, the ones who play a big role in success are not us as investors, but they are the holders of the projects we invest in.
From the point of view of understanding alone, it is clearly different then what will be equated.
In the gambling industry, only casino owners can get rich, while gamblers will only be people who slowly lose a lot of money, so the assumption that gamblers can get rich from gambling is just a joke.
At this point, we should understand that not everyone in the gambling industry can take advantage easily.
