Hi pantelis134,
One of the steps when erasing a device is removing the encryption key, effectively making the encrypted user data unusable. The device then uses a new key for the new user.
See here: Data Protection in Apple devices
Before selling your device, make sure to follow these steps to avoid selling an Activation Locked device: iPhone or iPad / Mac / Apple Watch
Hope that helped!
