The chances that you personally will be hit and killed by a meteorite? Effectively zero. Significantly smaller than your chance of being eaten by a shark while being struck by lightning.
The chances that a world-destroying asteroid will hit the Earth without warning are also effectively zero. NASA tracks all the medium-sized and larger asteroids that will, have, or may cross or approach Earth's orbit, and none (total zero) of the ones big enough to destroy a large area like a city are likely to hit us in the lifetime of anyone now alive.
