I uploaded my first video last week, reached over 100K views. Where do I go from here?

So, I made this video about GTA 6. It's a 20 minute video going in depth in a sort of mini docu/commentary kinda way.

I reached over 1K subs, and I assume it has more than 4000 hours of watch time, since the average watch duration is 6 minutes.

But the youtube partner program shows: 0 hours of watchtime.
Is this a matter of time before it updates? Or is there something I need to do?

I didn't bother to put non copyrighted music in, so sadly I can't generate income from it.
But for future videos, it would be nice in case my channel pops off and in case this wasnt just a lucky moment!
