yes

Not really.  A compiled program also tells another program what to do.
For example a compiled binary interacts with the hardware by making
system calls that are handled by the kernel or the video driver or .....

A program that makes direct hardware calls is severely frowned upon
these days.  Thus, except for the kernel and specialized hardware
drivers, all programs, whether they be binary executables (compiled) or
scripts (interpreted) actually interact in defined ways with other
programs (the shell, the kernel, the compiler, the interpreter, etc).
