Who said that Sauron could defeat Lucifer ? Lucifer is much, much more powerful than Sauron, Lucifer can create time loops and warp reality, Lucifer's true form would desintegrate Sauron. Sauron uses physical weapons and low level magic. Morgoth is also way stronger than Sauron, it's reasonable to say that Morgoth may be a threat for Lucifer (though Morgoth was also defeated by an ugly spider).
