What translates the public ip to the internal ip? Aren’t they different?

There's no translation between them. With IPv6, one network interface can have multiple IPs. A ULA (internal IP) is only used on your local network. Any internet-connected devices will also have a public IPv6 address.

ULAs aren't too common. A lot of IPv6-enabled systems only have one IP: The private one.
