It is only partly true. Stars have latitude and longitude just as we do on Earth, but they are called Declination and Right Ascension. A star that has a declination greater than 90 minus your latitude will never set. Such stars are called circumpolar stars. I live at 35° south so stars with declination 90-35=55° will never set. For example I can always see the Southern Cross.
