This is true. Reminds me of a somewhat popular youtuber who makes videos about "side hustles." One of his "main" side hustle is operating vending machines. He basically makes videos about how to operate your own vending machine business and so on. The irony to it of course is that 98% of his "profit" comes from youtube partner advertising. So he makes a few hundred bucks from the vending business but pulls 10k-15k profit per month from youtbe ads. So the real moral of the story here is don't waste your time doing a vending machine biz, focus on making entertaining youtube videos.
