So changes to any of the renderable UI stuff under it makes it have to recalculate the geometry for ALL the possibly-thousands of renderable stuff— which they mention, can cause noticeable multiple-millisecond CPU spikes. Realistically speaking, this may not be a problem if your UI is really simple but you can imagine that it can get unnecessarily wasteful as you make it more and more intricate. So having one giant Canvas for your whole UI is not recommended by Unity. And especially where performance is super important, separate the UI parts that get updated a lot from the parts that stay mostly static. You can also nest canvases, which allows designers to create large hierarchical UIs without having to think about where different things are onscreen across many canvases. Child canvases also isolate content from both their parent and sibling canvases. They maintain their own geometry and perform their own batching. So, no worries. The sample project in the course is doing the recommended thing in this regard. Good to know. The entire point of me doing these courses is to be comfortable with a base skeleton to make an RPG. I am willing to put the work in to hack all of the systems to make them do what I need them to do and be unique.

For example, this background scene could contain our aforementioned audio manager script and keep it alive throughout the entire game without ever having to de-allocate and re-allocate memory for it.
