Good “Hello World” Intro to Machine Learning for Curious App Developer?

My coworker asked me for a "good intro to ML." I would like to point him to a "ready to go" (Collab, Kaggle, Huggingface) notebook with good annotations/ explanations between the code blocks.

Can you recommend one? Something along the lines of this but with a direct link to a notebook, ready to run and with more expository text:
