You want me to double down on that for you? Randomness doesn't exist, it is only a function of we as observing not having all the information.

Picture a normal, 6-sided die. I go to roll it. As the die rolls from my hand and clatters across the ground, everyrhing slows into bullet time, until it freezes, and you get information. Physics formulas, forces, mass, little inconsistencies of the dice's weight and density.

If you get enough information- the precise details of my throw, every air particle that bounces against it, and a truely impossible number of other details, you plug the math into a supercomputer and have it tell you what side the die will land on.

It isn't random, it just depends on factors we don't have the capacity to see or understand enough to predict it.

This is why computers' random number generators litterally just take a hyperspecific measurement of the time and use that as the input to an equation to give you the number you're looking for.
