This isn't `du` resolving the symbolic links; it's your shell.
`*` is a shell glob; it is expanded by the shell before running any command. Thus in effect, the command you're running is:
du -s /data/ghs/14 /data/ghsb/14 /data/hope/14 /data/rssf/14 /data/roper/14
If your shell is bash, you don't have a way to tell it not to expand symlinks. However you can use `find` (GNU version) instead:
find /data -mindepth 2 -maxdepth 2 -type d -name 14 -exec du -s {} +
