Well since it's a long and complicated one that's what I'm confused about.

It's practically infinite... In order for it to be truly infinite we're need infinitely long URL's. But for all intents and purposes they're infinite, because 10^19 would equate to every person on earth making 1,461,879,944 links.

Then that'd be too many IMO.

Which it won't, by the way. They use 11 letters and at least the entire alphabet in capital and small letters, numbers, dash and underscore. That means they have (2*26 + 10 + 2)^11 many possible links before they run out, or 64^11. Written out, that is a number with 19 zeroes.
Right. Well, that's cool.

thanks for reminding me just how much i hate maths, by the way

That's the point: Youtube's system can deal with absolutely unreasonable amounts of videos, so they won't ever run into a situation where their technology stops working (they just need to add more hardware). If Youtube was built to handle a million videos or two or ten, then there would come a day when they'd run into trouble.

You mean arbitrarily long. URLs of infinite length are ones that literally don't stop, ever, and appear only as a theoretical construct in theoretical computer science.

No, you still didn't give the exact number with all digits corresponding to "pi".

Anyway, I owe you a hug and a smile for a sentence of a post yours few days ago.
Then I forgive you the physical impossibility that exists to write the whole number "pi" with all its digits.

So we are tied because of my kindness.

That's why youtube was made for unlimited videos.

I've tried explaining over and over why we don't need to know all digits of Pi. I'm not going to try again.
