style files for PS Cloud

So I just tried the Adobe Stock and downloaded what I thought was a style file for gradients. Apparenely this file is just a freaking photo or it is in .ai and unable to be uploaded as a style. My qestion is, does Adobe Stock have any style/overlay downloads or is this just a site where there are only images that are pretty much like a snag it from the web when it comes to this kind of file?  This is what I downloaded thinking it was a file I could addd ot my PS Cloud accont. I spent 2 hours with support trying to figure this out. If anyone has any better ideas please let me know. At this point, Stock is not somethig I think I want to pay for. what woudl be freaking amazing is to know that what file are compatible for the programs that I use.
