His list is based on top subscribers over all time, these people are fast rising to the top but are relatively new. Pewdiepie has been making videos for about a year (as someone popular) and is currently #18 on the most subscribed, the channels in the list compiled by rorrr are accounts that are ~5 years old.

Pewdiepie currently averages around 4,000,000 views per day, that's 120,000,000 per month which even at a really poor $1 CPM is still over $100k; at $2 CPM (or more) he'd be making well into 200k+
