If your Mac desktop is a mess of files and folders, you're not alone. A messy desktop must be common enough for a feature called Stacks to be included in MacOS specifically to ease that burden.
Basically, Stacks cleans up a mess of files on your desktop automatically by arranging them into organized groups of files that can be easily expanded with a click. It works well, especially if

How to enable stacks on MacOS Desktop
Do you have a messy desktop with tons of files? How to fix them quickly to organized stacks!
- Go to the desktop on Mac OS
- Pull down the "View" menu and select "Use stacks"
- All desktop files are now placed in neatly categorized "Stacks" for things like "Pictures", "Screenshots", "PDFs", "Documents", etc.
The effect is immediate and noteworthy, since some writing chips are instantly arranged in the stacks.
You can click on any of the "Stacks" to expand the files contained in that stack.  The files in the extended stacks can interact with just like any other item in the Finder or desktop, that is, renaming, batch renaming, moving, copying, cutting and pasting, dragging and dropping, changing icons, etc., are all possible within extended stack.
The animated Ima Ge displays the effects of Stacker on a messy Mac desktop, takes the scattered files and images and places them in nicely organized stacks.
You can also adjust how Stacker arranges files on the desktop of a Mac. The default is "Kind" (which sort by file type), but you can also group Stacks by different date options and file codes.
(Note that if you have multiple Macs with busy desktop computers and use the iCloud Desktop & Documents feature, the Stacks feature may be a bit busy as it spreads your desktop across multiple computers via iCloud. You can always disable iCloud Desktop & Documents on the Mac, but it will require all these files to be downloaded to the local Macs again.)
If you have completely thrown your towel on a neat desk and Stacks are not enough to twist it for you, You can also go the old-fashioned route and hide all desktop icons on your Mac, which effectively disables the desktop as a place to store something (but the user's desktop folder continues to be available from the Finder and other places that can browse the file system).
If the Stacks feature sounds something familiar to you, it may be because a similar feature has been available on the Mac, but especially for the Dock. The Dock Stacks feature extended docking capabilities in the Dock, allowing you to place items such as a recent item's stack on the Mac Dock and with some customizations available for how Dock Stacks appear and interact with. The Dock Stacks feature still exists in modern MacOS, it's only obvious to the Dock, while the Desktop Stacks feature discussed here, cleaning up the desktop.
You can always deactivate Stacks on your Mac desktop at any time, just by returning to the "View" menu and selecting the "Use stacks" checkbox.
