I mean, it would not surprise me at all if bot traffic on Youtube is larger as in bytes/s of video, than actual visitors.
Remember that Google has no interest in disclosing how many bot views there are.
There was this news article about Spotify banning some musicians accounts due to listen farming.

Since the payouts are not tied to the individual watcher or listener, scams run rampant. I guess the temptation to manipulate the money flow is way higher than having a "fair" distribution of each subscribers money to the artists.
Yt definitely makes an effort to prevent that. You can read up on how botguard's virtual machine works in some older writeups.
I watched today a couple hours of Youtube videos. How many bots are needed to match that much traffic?
if we're talking about requests it makes sense. I just have to open my apache/nginx logs to see how many bots are attempting to get in.
However I agree, on its face 73% sound ridiculous.
