Each volume uses only part of the overall container, so the available space is the total size of the container, minus the size of all volumes in the container.
On your computer, macOS is installed on a set of volumes known as a volume group. The volume group consists of one volume used for the system files (named Macintosh HD) and another volume used for data (named Macintosh HD - Data).
