You are probably right in more than 99%, not at all. There are more appropriate words to say that but I assume you use "debilism" fully consciously. 99% (or even more) of players lose money on gambling. Bookmakers statistics confirm it. I wrote this blog to show how statistics work, not to promote gambling.
Debilism means intellectual disability, in my opinion gambling is huge industry that made money on human ignorance. Every industry is like a cake (you should know sth about it), if you can take a piece of that - you can exist on such a market. Bookmakers earn money regularly - it's hard to say they are "intellectual disabled", gamblers that lose money regularly are. Most of players don't understand primary mathematical laws. I am not betting here. To understand you need read more than one post. Fortunately reading is definitely not a "debilisim".
