Less ageing, people still dying from starvation, diseases, wars—should be easy to imagine.
Ironically, if you would cast a magic spell that makes everyone on the whole planet stop ageing at 30, the situation in undeveloped countries would probably remain similar. It’s the developed countries that would have a problem.
If a population has an average birthrate of 1.5 children but a small subset, say Amish or Hasidic Jews have a much, much higher birthrate, then in the long-run the population birthrate will likely be much higher than 1.5.

In the long run, Malthus wins.
With birthrates of 1.5 children or less per woman that might not be true.

The Amish are a problem that’s quite separate from curing aging. They likely wouldn’t use it.
A population with a high birth rate grows exponentially even without curing aging.
