It only looks like RNG because you’re not observing enough of the hidden patterns. Those things provide you with the additional information you need to make logical deductions.
For instance, below is a spoiler about Gargoyles..
Gargoyles always (unless bugged) appear in pairs and face towards each other
Or a question you could ask yourself about Guardians
How many Guardians are there? Notice anything about their shields? Where do they appear?
Or a question you could ask yourself about mice
Is there any significance in the direction the mice face in?
