Congratulations for a great OP Bayan_D40. About the second reason you pointed out:

Reason 2: Social acceptability
Certain entertainment carries a greater degree of social acceptance compared to others. For instance, bingo is commonly regarded as harmless, while roulettes, sports betting, poker, or blackjack often carry negative associations, including addiction and irresponsible behavior.
Many people have a negative attitude to gambling, not even realizing that their passion for bingo is also gambling addiction. This case is interesting because people generally don't classify bingo or lotteries as forms of gambling.

What do you think? Why is there such a different attitude to gambling products and will it ever change?
Maybe the reason why people don't see bingo (or lotteries) as forms of gambling is that the risk of addiction is perceived also as lower, compared to other games like poker or slots. We make the difference between soft and hard drugs, so I would say that we unconsciously make the same comparison when we think about different games.
You're right that one can also get addicted to bingo or lotteries, but at least it seems that it is not so common. It would be positive if we could see the real numbers.
