How can I prevent my parents from tracking my Android phone or fake the location?
if you believe that your parents are tracking you with your android.do this

1:backup your favorite apps.
2:factory reset the phone.
3:encrypt your phone.(this way nobody else can access your phone)
4:for extra protection you may add pin so that you can lock down parents from accesing your settings.
5:if you are going a step further you can lock down your phone in kiosk mode with the help of any
custom launchers or anything like that.

but i think you should probably talk with your parents.
