I think that's why they call it "Creator" studio. Creators - in the way the term is usually used today - indeed do use many of these tools. Maybe you produce music, create a video about you producing music and also need an engaging thumbnail for YouTube.

In a feature film production, these would certainly be separate roles. But apart from maybe Logic Pro for composers, Apple's tools are not really relevant at those levels of the entertainment business anymore. Post-pro would be Pro Tools for audio, something like Avid Media Composer for editing etc.

I think Apple has realized they are not playing on that level anymore and target their marketing to where they are still in the game. That's not necessarily a bad move.
