Star Wars canon, small ships and hyperdrive

I distinctly remember in Star Wars, A New Hope, in the scene when the Millennium Falcon arrives at the remains of what was once Alderaan, a TIE fighter passes close by and Han Solo gives chase. Obi-Wan says "A fighter that size couldn't get this deep into space on its own." Is he implying that TIE fighters don't have Hyperdrives or that they are too far from Imperial space? I ask this because I distinctly remember that, at least by "ROTJ" X-Wings are very capable of hyperdrive as in the scene at the beginning of the Battle of Endor when the entire rebel fleet makes the jump into hyperspace including a squadron of X-Wings. X-Wings are not much bigger than TIE fighters. Thank you
