Barenziah mentions Elves living up to 1000 years meaning that could be a elves natural lifespan and 1000+ years could be from magical influence.

Gelebor saying he was around when Ysgramor arrived may means thats anywhere from 100 years to 5000 years or even older then humanities prescence in Tamriel. The Snow Elves are an even greater mysterey then the Dwemer, so no one can really say how long they live.

Generally give most Elves the ability to live 1000 years without a major magical connection but factor in every way to die.

Which there are 1000s of ways to die. They could even die from a Dragons shit landing on them.
