TL; DR It's because simple random sampling randomly chooses people without taking into account population subdivisions, whereas stratification is related to strata in the population based on categories.

Multistage sampling, also known as multistage cluster sampling, involves taking a sample from a population in successively smaller groupings. In national surveys, this technique is frequently employed to gather information from a sizable, geographically dispersed population.
Multistage sampling is used in this Gallup poll. For instance, they might pick a predetermined number of area codes at random before sampling a predetermined number of phone numbers from each area code.
The components from each stratum are present in the sample. In contrast, when using cluster sampling, the sample contains components from the sampled cluster. With multistage sampling, we choose a sample by combining various samples.
