How much do 1000 views make on YouTube?

I'm curious to know, how much can one typically earn from 1000 views on YouTube? It's a common question among content creators, and understanding the potential earnings can help motivate and inform their strategies. Is there a standard rate or does it vary based on factors like ad placement, audience engagement, and the niche of the content? Additionally, are there any other revenue streams, besides ads, that YouTube creators can tap into to monetize their content?
