Is setup_remote_docker default docker version on docs outdated?

Here stated that docker default version is currently 17.09.0-ce, but it seems to use 19.03.8 as default when I tried to use setup_remote_docker


Is the doc outdated, or am I doing it wrong to confirm docker version?

The version you are viewing is the version of the Docker CLI application. To view the complete version profile you’ll want to run docker version(see below).

With Remote Docker(setup_remote_docker) a separate instance is made available running a remote version of Docker. DOCKER_HOST is set to remote-docker which holds the IP of the remote host.
