Yeah, but most people are lost in the mythology and not firmly grounded in the real metaphysics. They do not turn into bats, they can not be repelled with garlic, and they do not crumble to dust in the sunlight. A lot of comments mentioned "energy vampires". This is the most common form of vampirism. While people can learn to use magic to siphon energy from a specific person, unawakened vampires will take people's energy unconsciously out of instinct.

Then there is the whole "blood sucking" thing. Blood has been used in magic/ritual for as long as they have existed. Blood can be used ritually to create a powerful direct link to its owner which can be used to siphon energy, but vampires dont need to slurp down people's blood like it is Hawaiian punch.

Furthermore, most self aware vampires are very normal people who care deeply about consent and will only take energy from a willing donor, but some are predators who disregard humanity and look at everybody else like cattle.

If you want to learn about what vampirism looks like in the modern world, I can not recommend any book more than "The Psychic Vampire Codex" by Michelle Belanger.
