To manage Database space you  generally have to think of two things: space in the tablespace and space on the Disk.  

Space in the tablespace refers to the space that the data takes up in the tablespace.   This is the data in rows and columns of the tables, the database metadata, e.g. things like indexes and statistics along with the definitions of the tables and other database objects.  The tablespaces also contain the OSM partitions.

Space on disk refers to the space taken up by the database files.  The tablespace resides in one or more of these datafiles.  The data files are a set size but they can be set to grow by a certain amount if they become full.  The datafiles do not shrink when space is freed in the tablespace.
