[25% OT] C library integral part of OS/kernel???

Is the C library of most OSes (i.e, unix type OSes) implemented at the
very low kernel or just outside kernel level?

Looking through the source tree of Linux/BSDs it seems like the C
library is intertwined with the OS (string.h and other headers are
there). So does this mean that when I program in C and use standard
library functions, it's similar to calling the OS specific APIs (same
type of performance)?

Seeing all these Standard Library functions being implemented at the
kernel/OS level makes me want to use C more, because it obviously means
other languages are implemented at a level "more distant" from the
system (possibly calling the C library functions????).

Is my thinking correct or am I way off? Am I getting too excited by
seeing standard library functions being implemented in OS kernel code?

Clarification will be appreciated.
