Not exactly. Each device transmits and receives at its full capability
up to the limits of the AP but 802.11b devices take much longer to
transmit and receive packets than 802.11g/n devices. That latency does
degrade faster devices' performance but it's not that bad. 802.11b is
not a problem at all for 5GHz WiFi devices. Devices operating at 5GHz
are unaffected by anything operating at 2.4Ghz.

IMO a more serious problem than throughput with 802.11b devices is that
they only do WEP. Isolating them on a DMZ with a dedicated access point
is a good idea and solves the throughput degradation problem as a bonus.
