Correct, enterprise wifi is usually just APs with a common SSID and security configuration and some tuning to try to force clients to roam sensibly. There’s no AP to AP comms, it all goes back to the switchport
There are solutions for AP-side roaming that is transparent to the client and whole network is visible as single AP, like UniFi "Zero-Handoff Roaming". Though because it forces whole network to use single channel it is deprecated in favor of 802.11r client side fast roaming.
