each game favored the fairness for the casino operators meaning gamblers is at either 60/40 winning chance or much lower.
in this case the longer player bet is the biggest profit owners gain.
60% losing chance while 40% winning chance, well, not bad at all.
We already know how casinos have run this business and it is their part also to take profit otherwise, they won't survive. That is why if we think about gambling, LUCK is very important. We have the skills and knowledge but this neither be enough to win. And this implies that gambling is not to be considered as a source of income (as a player) but this is a great venture for the owners.
