Well maybe you really should watch the video, then you also wouldn't say there is 0 chance for it to be manipulated.
Roulette can be manipulated with magnets and small bursts of air. In this video it really looks super off. The ball gets to rest at a number and then totally gets kicked out to go somewhere else. There are laws of physics and in this one these laws are out of the door. 

But anyway, in my opinion there is always room for manipulation, that's why I stay away from it as good as I can.
