Very few (if any) things in life on a non-quantum scale are actually random. Roulette results, dice throws, shuffled cards, etc, are all the results of complex and hard-to-predict processes, but they are no more random than the markets.

What people mean when they say that something is random on a non-quantum scale is this: the process is so complicated and hard to predict that our best models of the process incorporate a significant amount of randomness.

This is the case for markets too, where a multifractal random walk is about the best model we have.
