Distinction between apt-cache and dpkg -l

What's the reasons which lead such a huge distinction. I presume that dpkg is super than apt.

apt is for managing remote repositories, dpkg - for locally installed packages. They're related. apt is front end to dpkg. When you run apt-get install package it gets .deb file, and installs it via dpkg. So numbers differ because there's a lot of packages available, but only fraction is installed locally on your system.
apt-cache can show both installed and non-installed packages, because it queries the apt cache - listing of what is available in remote repositories ( that cache is what you get when you do apt-get update). For instance,
$ apt-cache policy terminator
terminator:
Installed: (none)
Candidate: 1.91-1
$ dpkg -l terminator
dpkg-query: no packages found matching terminator
