Looks like overview to me. Guys like Francois Chollet aren't going to spend their time doing an in-depth tutorial, and even if he spent the whole 90-minute lecture walking you through the specific thing he invented (Keras), it probably wouldn't be enough time to get a naive programmer up to competency. Each week is a different lecturer.
