Recently I have finished school and I’ve realised that most of my life since I was 4, I’ve been waking up at 6/7 am and I was just thinking why our body isn’t used to waking up early assuming you’ve had a good night sleep.

Do you mean waking up earlier than 6/7 am or that you are not used to waking up at 6/7am ?
Your body really like routine. We even have a name for the routine our body does in a day: a circadian rhythm.
When you go to bed and wake up at same the time everyday, your body will get used to it. It does it so well you won’t even need an alarm clock to wake up. Of course, other factors will play a role like the length and quality of your sleep and exterrnal cues like light and temperature.
If you keep waking up tired after following a good sleep routine for some time, you may have a sleep disorder like sleep apnea.
