Gamblers probably know such things, it's impossible that they don't know that, instead the majority just don't want to think like that. Then let's admit that even those of us who think of doing this just as entertainment, there are still times when we think that we might win when we play.
And when we experience a win, it brings a different feeling to us as if every time we play we will get a profit from it. The important thing is that we can still control it.
There are times my hopes are high to get a win irrespective of my taking the earning aide of it as secondary (not compulsory) on the grounds that my resolve is that am gambling for the fun and entertainment that is embedded in the activity but as humans been involved in an activity that money is involved that by chance/luck you can win an amount that can change your life, that inclination to earn from it will randomly offset at some point but it's left for the gambler who have accepted it to be a funfair activity to regularly remind himself that gambling isn't a source of making money so not to get addicted at it.
All gamblers will never escape the name of hope, although they may understand and know that gambling is only an activity for entertainment and pleasure, but on the other hand, sometimes they must also or have thought about taking advantage of the opportunities that are there even though there is absolutely no guarantee of anything to win except luck. Gambling is nothing more than an activity of fun and luck, and it is true that we as humans must have their own luck, and at least in our gambling journey you will definitely get occasional luck in a number of trials, and don't let you be tempted by that luck because it is really difficult to predict in any way, if you are lucky then enjoy that luck without involving any curiosity or greed in your gambling.
We have to be really healthy in looking at this gambling, I understand that there are opportunities there but we also have to think that there is absolutely no guarantee whatsoever to successfully take advantage of these opportunities, because everyone has their own time in terms of getting lucky, and because of that, gambling wins will continue to run randomly. This is not a place to make money at all, so we must remain cautious and remain in good control.
