Ubuntu Li-f-e Linux can be directly experienced from live media

Do I need to install Linux on my home computer from the USB media to use it?

No, the USB media created is a bootable live media which means that you can experience the entire Ubuntu Li-f-e operating system with all the pre-loaded applications without the need for installation.

For best experience and data persistence across reboots it is recommended that it be installed. It can be installed on a separate partition along with the existing operating system or in a virtual machine on a hardware with enough resources.
