This is not really correct.

First, some software is updated frequently in RHEL, including podman. RHEL 8 was released in 2019 and it has podman 4.0.2 from earlier this year.

Second, even software that isn't updated often, or at all, in the base system might have newer releases available as modules. For example there are recent versions of Python in RHEL 8, with just the basic runtime so that you can use pip to install more packages.

Third, the RHEL kernel is updated much more than the corresponding LTS releases. The RHEL 8 kernel is closer to 5.15-ish than to the nominal 4.18 release from which it was forked. Pace for backports has slowed down a bit, but there's interest in keeping the kernel up to date because people are running RHEL 9 containers on the RHEL 8 kernel.
