That's not the most pessimistic UN projection.
The medium variant projection by the UN forecasts that China's population will fall to ~767mil people with a dependency ratio of 102.8 by the end of the century.
The most pessimistic projection (low variant) forecast a fall to ~488mil people with a dependency ratio of 158.0 by the end of the century.
China has had the world's largest population since at least 1950 but is now projected to experience an absolute decline as early as 2023.

For the high variant, the UN assumes that China's average TFR would be around 1.9.
For the medium variant, the UN assumes that China's average TFR would be around 1.4.
For the low variant, the UN assumes that China's average TFR would be around 0.9.

The medium variant is a bit too optimistic. The UN previously predicted that China's population will start falling in 2031-32, but it already started falling in 2022.
The UN medium variant assumes that China's TFR will keep on increasing throughout this century, when there is no evidence to support this. In fact, if you look at the experience of other East Asian developed countries, China's TFR will continue to face a downward pressure as China continues to develop and urbanize.
Even Chinese demographers also think the UN is always too optimistic.

China's TFR already fell to 1.1 in 2021. The TFR in urban China has fell to 0.86. China would be lucky if their TFR doesn't continue to fall to 0.78 like South Korea as it continues to develop and urbanize their remaining rural population.
TFR in urban China:
Here's the projection from Shanghai Academy of Social Sciences, which assumes that China's TFR will average ~1.1 throughout the century:
For the first time in 60 years, China's population is on track to decline. Sustained decreases will have an impact beyond just China's borders.
