No matter what you study, of course, you will be an apprentice directly. I have practical experience when I study directly, but mostly theoretical knowledge when I study at school. You need to practice slowly before you can officially take up your post.

Of course, it is also beneficial to study at school for a while before becoming an apprentice. At least when you have learned theoretical knowledge, it is much more convenient to be an apprentice, because you don't know anything without learning. If you meet a bad leader as an apprentice, you will be embarrassed and won't tell you what to do.
