It might work that way, actually .
Just because the phone is encrypted doesn't mean there's not an exploit that makes it easier to bypass or extract the passphrase. Celebrite is unfortunately pretty good at attacking out of support phone and breaking into them.
Use a modern, supported OS on a device put out by a trusted vendor and you're probably ok. But old software/hardware makes it much easier to bypass.
Apparently some phones have a totally isolated electrically separated microcomputer which is in charge of encryption and decryption. Your phone doesn't actually know how the encryption decryption is done because it's separated from the microcontroller.
Any attempts to modify the microcontroller or replace any of its components with more cooperative components, will result in all of the data being wiped. This is implemented at the firmware level with the instructions being in ROM.
