Not always - due to the need to program the device at some point during production it can be much more cost effective to put a flash device on and program it after the hardware has been assembled. It allows the use of an off the shelf component, which is normally a win, and can be useful to allow production test access to the system.

if you look at volume pricing of parts flash is still frequently more expensive then ROM (One-Time-Programmable) versions, let alone ones that don't have the flash at all.

also programming the flash frequently requires additional wires and other components in the device, which also cose.

Yes, it does depend on what you're doing - volumes, feature sets and whatnot. Point is that you can't tell which of flash or ROM will work out better until you look at the particular application.
