He can move much more quickly than a normal human and so fighting in hand to hand combat gives him a distinct advantage. They also appear to gain some instincts for how best to use that new strength, speed and endurance, and so are going to automatically be better fighters than human.
Skill must still be taught, though, and it's generally up to a vampire's creator to train him to protect himself and hunt. Not all vampires will have the same level of skill at martial arts, though it's likely that most of them will have some skill, due to their predatory nature. Presumably, those who are Kung Fu masters have spent centuries perfecting this ability, while newer vampires will simply have basic self-defense and hunting skills.
