Your whispers of Ubuntu's allure, a siren's call to rebellion, beckoning you to slip into its arms, free from Windows' tender grasp.

Yes. Think of it like a live operating system that is using your hardware to run, but isn't installed on your hard drive. It's using the USB as a hard drive.

then I just need a usb and download the Ubuntu to play around, right? Any Ubuntu release, or a special one? Which one you are proposing?
