That vase shows up everywhere. It was on Thingiverse for years before Printables even existed.

If you browse filaments on Amazon right now you're likely to see that vase model as an example of the filament in the pictures.

If you go on etsy, you'll see that vase being sold and has been sold there for years.

To showcase fancy filaments, YouTubers will often print that specific vase.

It's been printed millions of times worldwide.

That vase was featured on Daily Dose of Internet twice (not that that matters much but it's an interesting thing considering that Daily Dose doesn't usually care about 3D prints).

If you've been in the hobby for five years but don't know about that vase, you've been living under a rock.

I actually asked Gemini for an estimate of how many prints of that model exist worldwide and it said "1.5 million and 3.5 million prints". Based on all of Google's collected statistics about it on the Internet.
