Untill the administrator doesn't specify QUOTA or grant UNLIMITED TABLESPACE to user Oracle account doesn't have available space in any tablespace, event in default:
SQL> create user new_user identified by new_user
  2  default tablespace users;
User created.
SQL> grant create session, create table to new_user;
Grant succeeded.
SQL> conn new_user/new_user
Connected.
SQL> create table t(x int);
create table t(x int)
ERROR at line 1:
ORA-01950: no privileges on tablespace 'USERS'
SQL> conn / as sysdba

SQL> alter user new_user quota 1M on users;
User altered.
SQL> conn new_user/new_user
