x$kzsro is a fixed table. You can select from fixed tables only if you are connected as sysdba. You can't grant select on a fixed table to a user:
SQL> grant select on sys.x$kzsro to scott;
grant select on sys.x$kzsro to scott
ERROR at line 1:
ORA-02030: can only select from fixed tables/views
SQL> What you could do is as k your DBA to:
SQL> create view v$kzsro as select * from x$kzsro;
View created.
SQL> grant select on v$kzsro to scott
  2  /
Grant succeeded.
SQL> connect scott
Enter password: *****
Connected.
SQL> select * from sys.x$kzsro;
select * from sys.x$kzsro
ERROR at line 1:
ORA-00942: table or view does not exist
SQL> select * from sys.v$kzsro;

P.S. If you are new to oracle starting with sys owned tables and fixed tables isn't the best choice.
