at quick glance, the videos seem to be in 1.5 - 4 minute range, so taking 2.5 minutes as average, youtube-dl fetches 8 MiB. I don't know what policy does youtube use for storing lower bitrate encodings, but I figure they only keep them temporarily for some time since it was last requested and encode it live. so 2000000*8 MiB = 16 TiB, not counting whatever redundancy they have. with the 20M views that guy has got in total, they probably make more money off him than the storage/bandwidth/compute costs
