These lectures give a more theory based approach, while the book is more based on discussing practical systems; now both are covering distributed systems as such.
Now the distributed system audio course on youtube is extremely accessible (i listened to them while taking walks with our dog)
The book is also great, Kleppmann is writing in a very accessible style.
What that means in practical terms is that you'll be presented with diagrams and need to pause and think what they really mean.
This context will likely not be translated well in the audio form.
