Getting Started - Basic Questions

I had some basic questions about the programs and how they work.

If I purchase a program - looking at FB Strong - are these the exact same videos that are available on youtube for free? Is the difference just that the program is giving you a guide for how to use the videos.

Also, I used FB 7-8 years ago. For these programs, are most of the workouts more recent videos? I feel like I could connect to videos made in the last 1-2 years but watching a video from 2014 would feel off.
