Why I cannot select on user_tables, user_views etc when I am DBA?

Question

I came across something odd:
I am logged on as DBA, when I do:
Select * from user1.user_tables
It gives me
ERROR at line 1:
ORA-00942: table or view does not exist
I know I can use:
Select * from dba_tables where owner = ‘USER1’
but I am DBA and I can do select on every other thing in USER1 schema; why do I get errors on such statements.

DEFINE B='YOUHRIS'
Prompt USER INFORMATION
SELECT
' User '||username||'''S Account Information',
' Account Status => '||Account_status,
' Default Tablespace => '||default_tablespace,
' Temp Tablespace => '||temporary_tablespace
from dba_users where username=upper('&&B')
prompt OBJECTS OWNED BY USER
select a.username LoginId,
'User '||nvl(b.owner,'Does Not Own any objects..') ||' Owns ' ||nvl(b.cou,0)|| ' Nos Of ' ||nvl(b.object_type,'Objects')
FROM
dba_users a,
(SELECT OWNER,OBJECT_TYPE,COUNT(OBJECT_NAME) cou FROM DBA_OBJECTS GROUP BY OBJECT_TYPE,OWNER ORDER BY OWNER,OBJECT_TYPE) b
where a.username=b.owner (+) and a.username=upper('! &&B')
Prompt SYSTEM PRIVIELGES GRANTED TO THE USER
SELECT
nvl(b.grantee,'No_System_Privileges_Granted'),nvl(b.privilege,'null')
from
dba_users a,dba_sys_privs b
where a.username =b.grantee(+) and grantee=upper('&&B')
Prompt ROLES GRANTED TO THE USER
SELECT
nvl(b.grantee,'No_Roles_Granted'),nvl(b.granted_role,'null')
from
dba_users a,dba_role_privs b
where a.username =b.grantee(+) and grantee=upper('&&B')
