I don't understand it technically deep but I see some illustrative explanation with similar information on impossibility of finding Bitcoin private keys like finding an atom in a universe.
Those explanation are close to this thread's topic but those are about "
private key collision".
Which explained the whole private key range's search space and the possibility of randomly generating the same private key.
On the other hand, the reply is about "
pubKeyHash collision" (
a.k.a address) which about (
in summary):
The possibility of multiple different private keys that could generate the same pubKeyHash.
