I realize this is computer simulated mechanistic analogy to
a living biological cell, but just how far amiss is the
depiction? Does it bear any correlation to the functions
that take place inside the cell? Fascinating

I only watched the first one. The written subtitles were generally a
correct depiction of the events of DNA transcription, intron-exon
editing, and translation to protein. The video was completely
misleading making cellular proteins behave like complex spacecraft
smoothly coordinated are carefully organized. The process is actually
quite messy with all sorts of molecules careening around bumping into
things and the "correct" molecules bumping into the wrong place or the
wrong angle until it eventually gets it right. Only the "correct"
collisions, the ones with the right molecules at the right orientation
in the right location, stick. The others just bounce apart. But
there are such an incredibly number of molecular collisions that the
whole process works quite well.

I don't know just how much is possibly in modern molecular biology
labs but my impression is that pretty much every step can readily be
done in vitro. How the machinery works is no mystery and readily
obeys all the laws of biochemistry and physical chemistry.

IIUC these videos are not simulations but animations. The former uses
mathematical models to drive to drive the actions, the models
representing the system being simulated. The accuracy of the
illustrate actions depends on the mathematical models. For example,
this video is an actual simulation:

Animations are simply moving pictures whose actions are controlled by
the animators. Computer animations use the computer to relieve the
animators of low-level and/or repetitive details, but the computer
doesn't predict or direct the overall actions. The accuracy of the
actions depends on the director of the animation.

The distinction is important to your cited videos. The narrators make
a point of how the cells are actual machines. But the machine-like
behavior isn't deduced from a computer using mathematical models.
Instead the machine-like behavior is a consequence of the director's
assumptions that cells are designed.

IOW your cited videos inform only how the directors chooses to inform.
That they illustrate any underlying reality is strictly coincidental.
