That's correct albeit confusing behavior. The source package name is always linux-source-x.y.0 regardless of the actual (upstream) kernel version that it provides. If you really need upstream version 6.5.0 you need to install a specific/old version (6.5.0-5.5 in this case) of linux-source-6.5.0. But those early versions are pretty much development versions and prone to have issues...
If you care about upstream kernel versions you should use the git repo [1] rather than the linux-source-x.y.0 packages.

Querying apt show linux-source-6.5.0 reports: [...] Description: Linux kernel source for version 6.5.0 with Ubuntu patches This package provides the source code for the Linux kernel version 6.5.0. [...] So providing 6.5.13 seems like a bug to me. But it's my first time trying to build a kernel module for Debian myself, so I'm quite unsure what's happening here. Any pointers welcome.
