The fact of the matter is that most of the time people do gamble knowingly full on that they will lose because there is a house edge however house edge works on long periods of times and this just shows even tough with house edge you will lose long term, there is always that short bursts of winning chance for you with one big winning changing your luck chance to your favor. Doesn't always happen every single time you gamble but this shows there is that chance.
Yes, most of the players already know about the house edge but I still doubt all of them are already understand on that or not. Because I still saw there are still people complaining about the house edge and being not provably fair as well just because they losing on particular site. And btw by mean of short burst, I do not think it will work on everyone, depends on what startegy that you are using though. Big multiplier is good if you can manage your bankroll to play though
