You can't use variable expansion in /etc/environment (which is why you see an unexpanded $PATH in the output from echo $PATH). /etc/environment is read by the pam_env module not a shell script so just simple assignments.

The default PATH is set in /etc/profile. Users can modify their PATH by editing ~/.profile, ~/.bash_profile or ~/.bashrc (if they're running bash) but if they don't they will still have a PATH as defined in /etc/profile.
