Use MONTHS_BETWEEN to get number of months, divide by 12 to get years and then use FLOOR to remove digits after the decimal point:

SELECT FLOOR( MONTHS_BETWEEN( SYSDATE, date_of_birth ) / 12 )

To answer your second question, TRUNC(SYSDATE,'YYYY') returns the date TO_DATE('01-JAN-2003') (assuming current year is 2003).
