I just recently found out that routers connect you to the internet, but then I found out that ISPs also connect you do the internet. Can someone explain to me what really happens behind the scenes? Why do we need ISPs if our routers can connect to the internet by themselves?

Your router connects your computers to each other, and to a computer owned by your ISP.
If you don’t have an ISP, the various computers and devices in your house can upload and download information to each other, but there’s no path for information to flow between your house and Reddit (or Google, or the tiny company that’s somehow still hosting this one obscure niche site from 2003).
