LET ME START SAYING I KNOW GAMBLING IN FRENCH IS NOT WRITTEN AS THAT AND I DID IT THAT WAY FOR COMEDIC EFFECT.

Moving on...

Usually, I don't explain a joke but since people may not know the reference let me give you a little tour on art story. This is a reference of a famous painting from Rene Magritte. The idea is while the painting pictures a pipe, a picture is a representation of an object but not the object itself thus "this is not a pipe (but a picture of one)". Basically, Magritte was a troll who meme'd way before the internet was invented.

The comic follow the same idea. While it obviously pictures some sweet, sweet gambling, it's not gambling, but just a picture of gambling mechanics, no matter how hard big game companies try to say otherwise to prevent the government to crack down on them.
