You either have to assume that the process is actually quite easy once you get the hang of it, or that there are genuine billions of people watching every single BTS video on YT. I will take my chances with the first because the other reality is way too fucked upHow realistic is that process to repeat, anyway? The instructions make it seem like the process is incredibly inefficient. Assuming 500 people actually bothered trying it, I'd be surprised if they actually boosted the views more than 5000 total viewers.
