How does this YouTube video automatically update its title?

I came across this YouTube video:

https://www.youtube.com/watch?v=VTU69_L8i8s

The title keeps updating with the latest statistics like views, likes, comments, subscriber count, and even the number of days since upload.

I'm a complete beginner, so I'm curious how this is possible. How does the title update automatically every few minutes? What APIs or tools are used, and what's the overall workflow behind it?

I'd really appreciate a beginner-friendly explanation. Thanks!
