For everyone wigging out about the movie it REALLY helps to know comics canon here. The snap (people turning to ash/dead) isn’t permanent. Do I know that everyone that dies as a result of it comes back? No of course not, but in the comics the snap is undone.
Personally I think the fates that are settled earlier/elsewhere in the movie are more likely to be undone but dudes, it’s part one of a two part movie. They did a good job making sure ya’ll come to part two.
