When RHEL releases (sources of) updates, then Rocky, Alma, and CentOS Linux start to build. How long it takes for each of them depends on their build systems. Yes, all three can be expected to release equivalent updates.
However, this thread has discussed a different bottleneck: mirrors. Once each project has built new packages, they sync to their mirrors. Mirrors of Rocky had some issues in the Summer.
Overall, RHEL has not released many updates lately because their development is currently focused on the next point update (now in public beta stage).
