Anyone coming from a development background will entirely get the idea of stable releases. 23.10 or 24.04 are just rolling releases of a stable distro. It's the production ready version. You can choose to opt-in to the development updates at the risk that your system might be slightly more unstable, but that's not a decision that a casual user should consider.
The version numbers on Ubuntu specifically, are just dates. 23.10 is the stable release from October, 2023. That's all it is and there's really no point in thinking about it deeper than that. It's a date, not really a version number.
