USER_TAB_COLUMNS describes the columns of the tables, views, and clusters owned by the current user. Its columns (except for OWNER) are the same as those in "ALL_TAB_COLUMNS". To gather statistics for this view, use the DBMS_STATS package.

The USER_TAB_COLS view can display system-generated hidden columns and invisible columns, which are user-generated hidden columns.
