Does the country not allow people to live to be over 120 years old?

The length of national life depends on the social situation of the country, and poverty, disaster and war will reduce national life expectancy. If a country really has many people who live long, it means that the country's development and economic strength have reached a corresponding level. Of course, the state will not force people who live long to die. Only a stable and suitable life can lead to a long life. Moreover, the state will adjust its policies at any time as the population changes (such as family planning in China), and will not wait until the state can't afford to kill people.
