Timmy did however spend years and years training on his own data ingested from incredibly high quality sensors. Not sure what your point is

He does ingest a lot of frames of input consisting of mostly that.

What’s the FPS of human eyesight? How long did Timmy spend looking at Mario, more generally other cartoons and even more generally human forms? Do the math and you’ll find he’s got a pretty big training set as well, maybe not quite the same size but nothing to sneeze at.

I mean… neither did any AI.
