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.
There are many players who play without a strategy, they just choose several teams that they unite in a parley, to get a good odds, this is their entire strategy. There are no strategies for slots, I don’t know what strategies can be applied there. Trading is a completely different matter, there are trends, support and resistance levels from which you can build your actions, in gambling everything is different.
