How can some contributors get so many downloads with relatively few assets?

I noticed these examples in the Adobe Stock Top Sellers:

• AntonKhrupinArt: 28 pages — 100,000 downloads
• Tanya Shulga: 21 pages — 100,000 downloads
• dlyastokiv: 100 pages — 250,000 downloads

How can contributors with only 20–30 pages of assets reach 100,000+ downloads?

Does Adobe Stock's download count depend mainly on search ranking, content demand, keywords, asset age, or individual assets being downloaded many times?

I’m trying to understand how a relatively small portfolio can generate such a high number of downloads.
