Zigbee is the wireless network protocol. The equivalent to it on the Matter side is called Thread, also based on Zigbee from what I read (was developed by Connectivity Standards Alliance, formerly known as Zigbee Alliance). Zigbee and Thread operate at OSI L1-3, Matter is L3/4-7.
Matter is a communication protocol adopted by a lot of manufacturers but I think practically for the buyer the real benefit is that you no longer need a bucket of hubs for each of the device ecosystems one might use. It's more future proof so it makes sense IKEA would add support for it in their hardware including existing hubs I believe.
