How to uninstall jupyter

I have been trying to uninstall jupyter

I have tried the following commands

pip uninstall jupyter
pip3 uninstall jupyter

and

rm -rf /Users/$user/Library/Jupyter/*

Even after running all these commands when I type jupyter in the terminal I get the following message

usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir]
               [--paths] [--json]
               [subcommand]
jupyter: error: one of the arguments --version subcommand --config-dir --data-dir --runtime-dir --paths is required

What exactly is going wrong and why am I still able to use the command?
