We just have to remember that it's still gambling and not trading. Strategy works more in trading than gambling as the market it's self tend to repeat past actions but not the same idea in gambling. Though having a good gambling strategy would help your improve your gambling activities and reduce the risk of becoming a loser in gambling. Most people employ strategies created by them selfs to help management their risk. It's gambling so I don't think it makes sense to use someone else's strategy to manage your own risk. Just play your games with vert little risk and you might be able to beat the losses when it comes.
Yes I agree with you, indeed the strategy works more on trading not on gambling, especially on slot gambling, which in my opinion in this gambling is purely there is no strategy at all to be able to get profit other than luck that is in ourselves. Maybe some people do have their own strategy but not a few people also look for strategies from other people such as streamers who do influence some of the mindsets of gamblers. In addition, the loss actually depends on ourselves how we do the gambling, for example if we gamble with a financial limitation that is allocated relatively small then the risk of loss will not be too big and will not be a serious problem.
