Definitely, some user doesn’t know what is the house edge or how the house edge works which is why some user still doesn’t know that casino earn through this edge.
Worse still, you will hear some users talking about concepts such as the house edge, but they don't really know what they mean. Everyone who has been in this world for a while is familiar with these concepts, as well as RTP. But then in many threads you see how, in reality, there are people who, even though they are familiar with these terms and use them from time to time, don't really know what they mean.
In a forum where we all had a perfect grasp of these concepts, a thread like this would never have been created.
