Need space in Icloud

The files from iCloud should be completely synced when Mac and other devices are signed in with same Apple ID and password on the network , in which desktops and documents box , iCloud Drive should be turned as on Access and manage your files in iCloud Drive - Apple Support

Note : when you remove Mac from iCloud account it won't erase files from other devices like iPhone / iPad or other Mac , the Mac will be removed and its iCloud features will be inactive from it .

Getting Space in iCloud:

One unique method...

Download All of iCloud:

If you wanted to, you could download all of iCloud, and then trash what is in there. When trashed, it would be empty, and you will start it anew. Perform my User Tip: Getting a Quick and Direct "iCloud Drive-to-External Hard Drive" Download - User Tip. All would be saved, and would then be removed —photos and all. You would then use Finder to browse all of iCloud.
