Yes, that's true.
But I'm always a bit sceptical about such approaches. They are not universal. You still need glibc/musl to be the same on the target system. Also, if you compile againt new glibc version, but try to run on old glibc version, it might not work.
These are just strange and confusing from the end users' perspective.

Why would you include most of your dynamic libraries but not your libc?
You could still run into problems if you (or your libraries) want to use syscalls that weren't available on older kernels or whatever.
You can include it, but
- either you use chroot, proot or similar to make /lib path contain your executable’s loader
- or you hardcode different loader path into your executable
Both are difficult for an end user.
This isn't that hard (that's not to say this is easy, it is tricky). Your executable should be a statically linked stub loader with an awful lot of data, the stub loader dynamically links your real executable (and libraries, including libc) from the data and runs it.
