Both sides have their points: some don’t believe, and others do. We just need to respect each other and never say it’s impossible to be profitable in gambling, because if you think that way, maybe gambling isn’t for you.
I highly agree with what you stated. People have different experiences in gambling even if they are playing the same game. For example, gambler A is fond of playing Pragmatic Play games and gambler B is also the same. The experience of Gambler A varies from the experience of Gambler B. Like Gambler A may experience continuous winnings while Gambler B may have consecutive losses, We cannot blame Gambler B for cursing the game provider due to his bad experience while Gambler A is praising the game provider.
This scenario shows opposite stories so maybe those who observed Gambler B may think that it is impossible to win in gambling while those who witnessed Gambler A consecutive winnings may think it is much easier than looking for a job.
Regardless, when engaging in gambling we should always think of the worst scenario and accept and let go when things don't end up as expected. Just remember, to minimize the possible financial ruin, we must always gamble what we can afford to lose and always gamble responsibly.
