That depends on what you mean by all this, if you mean that this provably fair system is made to get money out of players then it's not true, if you mean that numbers are not really so random (even though site owners have nothing to do with that) then you are right, ofcourse they are not completely random, and they will never be.
I dont dispute the random generation number, my problem is with the presentation problem.
It should be dead simple for the user to understand what the hell is going on and unfortunately it is not.
