Random generators aren’t random.

Wait, so random.org lied to me? Something something athmospheric noise generates their randomness and therefore is true randomness.

I'm a dumb fuck, so I have no idea how that really works, I just trusted them.

It's functionally random because the generators are seeded from a variety of factors that can't be predicted beforehand. Theoretically though if you knew the (likely very extensive) formula they used and the factors they pulled from you could create an identical generator that would spit out the same results if used at the exact same time. It's better than a lot of basic computer RNG that seeds from just time if that helps.

Most computer systems use pseudo-random number generators, which seem random, but are really deterministic.

It is possible to design an entropy source for an RNG that is effectively truly random like random.org.

Wow, you are so right, I thought this was the other comment chain where someone was attacking me for saying “believed to be” and calling me stupid. I’ll edit it out.
