Randomness is about a lack of feasible means of predicting outcomes. Even in these quantum reactions, I believe there's a tiny undiscovered coppersmith-quark or scout-quark that all along would have dictated a certain rate of radioactive decay by its presence, we just don't have a way of observing it and understanding it.
If you are three and watching your first Disney movie of your whole life, whether the villains will cruelly end the plucky protagonists' life or fall to the protagonists' ingenuity and bravery can be equally random, it's a matter of perspective.
My comment about pi, based on its circular logic that renders it useless from any sort of application with utility, seems philosophically correct to me.
