He's got around 65 million views in 8 years that's around 300-400 thousand dollars American before taxes, even if most of that's from the last 4 ish years that's still less than $100 thousands a year. Not bad but nothing crazy, that video only has 26k views so far probably not even making a couple $200 so far even if the views double that's a fair bit of effort to make $300-500 dollars.
