It’s a satire on how deeply some fandoms read into lyrics or “hidden messages” from artists and works of art in general

to me it reads as a well done parody on conspiracy theories.

right! that's it, its like this nonsense numbers conspiracy theories that seem ramblings of some mentally ill person, but written in a more coherent, interestnig way that any of these (they usually are harder/cryptic to read due to its nonsense) so it ends up being an easier read as a parody than an actual conspiracy theory
