Your second bolded part answers your first question. The Blessed Virgin Mary may not have died as a divine gift - a gift from God. She was simply brought to Heaven body and soul at the end of her Earthly life.
I posted some above after quoting you: I am copying them here so you don't have to search-
From Wiki: was only relatively recently defined as infallible dogma by the Catholic Church, and in spite of a statement by Saint Epiphanius of Salamis in AD 377 that no one knew whether Mary had died or not. Why wouldn't Mary have died? She was human right?
"having completed the course of her earthly life," leaves open the question of whether the Virgin Mary died before her assumption or whether she was assumed before death; both possibilities are allowed. Mary's assumption is said to have been a divine gift to her as the 'Mother of God'. Ludwig Ott's view is that, as Mary completed her life as a shining example to the human race, the perspective of the gift of assumption is offered to the whole human race. Yes, I'm confused. What exactly is assumption?
I see other "denoms" believe in the assumption as well.
From Eastern Christianity Comparison (is this part of the Catholic Church?)
Many Catholics also believe that Mary first died before being assumed, but they add that she was miraculously resurrected before being assumed, while others believe she was assumed bodily into Heaven without first passing through death. Huh?
While there is a definite dogma that the Blessed Virgin Mary was assumed (taken to heaven body and soul) that dogma does not state how and if BVM died first. It is left to the individual Catholic to decide what he/she believes about. Some say she died and at the moment of death was assumed to Heaven. Others say she was assumed to Heaven just prior to death.
Eastern Christianity includes the Eastern Orthodox church. As Asta and I very breifly discussed a few posts up, the Great Schism of 1054 was where the Church split "officially" into East and West.
