Not necessarily - the 'eight hour sleep' is a myth. Every person is an individual - while one person might need 8 hours sleep each night, another might only sleep for 7.5 hours. I, myself only need just over 6 hours each night - and have had this sleeping pattern ever since I was a teenager (over 30 years ago !)
boys sleep longer because they sleep 9 hours to 11hrs and girls just sleep 7 hours to 9 hours
