It means exactly that. Open applications consume memory. Once that memory is used up, you need to close applications to release it if you are not using said applications.
Close open Apps you aren't using to release memory for other apps to use.
How much memory does your Mac have? You can see the memory in Apple Menu->About This Mac.
You can also see what is using memory in the Activity Monitor App. click here-> Activity Monitor User Guide for Mac - Apple Support
You can find Activity Monitor in the Utilities folder in the Applications folder in Finder, in the Launchpad on the Dock, or by using Spotlight search.
