Decided to do some libre study all about randomness. True randomness vs pseudorandomness, RNG, PRNG, the metaphysics, and any and all applications of it.
Any suggestions for study material?

You can study Pokémon breeding and the assignment of natures and IV's.

There's nothing you'd want to know. It's quite boring.
True random numbers have zero autocorrelation, ie no patterns. Quantum process are truly non deterministic. Pseudorandom numbers are deterministic so they have small autocorrelation although the goal is to try and minimise it. RNG mostly comes from radioactive sources because it's a quantum process, or other things such as hardware thermal noise. PRNG uses mathematical formula and a seed with high entropy to mimic randomness. Therefore, it is deterministic.
That's it. Nothing magical.
Applications are mostly in crypto, Monte Carlo simulations and graphics games etc like random trees.
If you want to study, read those topics

This isn't necessarily true.

If a PRNG is seeded with a 64-bit number that is known to be truly random, and the PRNG is used to output 1024 bits, what can be said about the entropy of that sequence?
It seems that there is the mathematical sense of entropy, which depends only upon the generator; in other words, a good PRNG will produce a high entropy looking sequence regardless of the seed. But if an adversary knows the seed that was used, then the sequence has a metaphysical "zeroing out" of its randomness. So there's a weird collapse between what can be mathematically expressed and the true state of knowledge in the universe.
What can explain this madness?

depends on what you mean by deterministic
people incorrectly assume that superposition means "unknown", " simultaneous", "OR" etc when superposition is an irreducible concept of a state that is unlike anything in macroscopic world
so if you define deterministic by some reference to human experience then no, they cannot be deterministic
QFT further complicates this because probing say an electron at sufficiently high resolution makes the concept of an exact position meaningless as the "true" position keeps changing
if by deterministic you think that behaviour of small but sufficiently complex system is exactly predictable based on its constituents, then it's not true either with the simplest example being atomic decay
it is true that quantum processes are not necessarily non deterministic because nonlocal hidden variables can explain all that pesky randomness away so randomness is not a conceptual necessity for quantum processes
however contingency only allows for something and does not guarantee it
point is, determinism by most definitions is impossible to exclude on a logical level but anyone with a working set of eyes can tell these processes are not deterministic in any capacity

i hate to say it but as a former smoker of nearly ten years, and having to deal with friends who smoke for longer periods of time, i have to admit it.

Classical thermodynamics defines entropy as relative to absolute zero. When you discover the algorithm, the seed, or the details of how the seed came to be, the number changes but one end of the scale is still attached to the same spot.

Running the PRNG increases entropy in the thermodynamic sense. Information theory doesn't have an explicit concept of heat or work which is needed to increase entropy, so they disregard the 1024 bits of entropy as soon as they find out it came from a 64 bit seed.
