“The various flavors of Linux don’t use their own version of the kernel.”
RedHat has several of their own custom versions of “the kernel”.

No offense intended but Redhat can suck eggs. My least favorite distro.
“The Kernel” is https://kernel.org.
Most/all of the distros post kernels that are often based on a well-known base version and then patches are applied via the distro’s package management system. Those patches are often based upon the deltas required to get from the base version to a more recent version of the kernel as posted on kernel.org. The patches may also include updates to accommodate quirks in the distro. As the target hardware is unknown, kernels supplied by the distro maintainers are often bloated and include every module known to man. You can use the distro’s kernels or build your own custom kernel which is tailored to your hardware. Personally, I use the long-term support kernels directly from kernel.org.
Custom non-public kernels arise when there are proprietary device drivers and/or features offered by company XYZ. I’d wager a guess that the alphabets have their own proprietary kernel hacks.
