Are many students and many students of the same part of speech?

Many students and many students have different parts of speech, the former is an adjective and the latter is a pronoun. When many is used as an adjective, it is followed by a plural noun, which means many identical people or things (but the number is unclear). When it is used as the subject, its predicate verb should be plural. Pronouns are often used in many sentence patterns. When they follow nouns, nouns should usually be specific (such as the, the, the, my, our, Tom's, etc.). For example:
