In summary, no, there are no differences. It's the same content blocks presented in different places.
The training path simply allows us to offer certain course lessons in an order that we believe is pedagogically relevant. However, you are free to access the courses independently as well.
It's possible that only certain lessons from a course are included in a training path, so if you want to see the entire course, you can search for it directly and access it. Progressing through a course is not tied to your training path, so a lesson completed in your training path will also be marked as completed in the platform overall, and vice versa.
