This is not (usually) true. A controllerless modem has a DSP to do the signal processing, but no controller to handle the 'AT' commands and control the DSP. These are what are usually called winmodems. There *are* modems with no DSP, little hardware, except for the line interface circuitry. These are usually called "soft modem"s, where the signal processing is done using the host CPU. These save the < $5 cost of having a DSP on chip. But when the consumers yell 'give me cheap'...
