Just to push back on this slightly, I'm sure I've watched Youtube videos with someone who bake cakes for a living who said they used boxed mixture for most of their baking.
As others have said elsewhere, some of the ingredients involved are not easily available/cost-efficient for the home baker. This means it's more than possible that you will get an objectively better cake from a mix, e.g. from blind tasting.
This does depend on the type of cake you're baking and your expectations of 'better' though.
