In the long discussion we stray from many of the main tropes. However, what I think is that if someone is gambling to win the jackpot or a large bet, then it is not right to gamble. Because there is no certainty in gambling. It depends entirely on luck. Learn to enjoy this gambling and at some point you may even succeed.
So you are saying to gamble only for fun and nullified the aim to hit jackpots? I think it can't be helped to aim extra aside from having fun in gambling. I also think it won't hurt if aside from having fun in gambling, we aim for possible jackpot win as long as it is in line with our gambling activity, plans, and budget. Taking extra targets while we are on enjoying the game adds more excitement IMO. As long as we don't need to do extra or spend an extra amount during our gambling session, it is ok to aim for a jackpot if the opportunity presents itself.
