To make it clear, casino was designed to make people have entertainment playing it using their money.
That’s the wrong perception. Gambling is designed to deliver fun, but the reality is we all lose in the long run.
No way. Casinos are businesses and, as such, they were designed to make money and maximize profits. Just think about how, in the US, gambling was run by the mafia when it was illegal. Were they thinking about “entertainment”? No, they were thinking about making money, just like with prostitution and drugs. Another thing is that as a gambler, you should take it responsibly and play for entertainment without expecting to beat the house edge because you won't be able to.
