In English sentences, why are there sometimes attributives and sometimes adverbials behind nouns?

Attributive is used to modify nouns or pronouns, so let's see if the latter part modifies nouns. If it is, it is an attribute. But there may be no attribute after the noun, but an adverb modifies the predicate verb as an adverbial, for example,

The boy rushed out to play. Urgent use is located after the noun in this sentence, but it has nothing to do with the noun boy but modifies the predicate verb, so it is an adverbial. Another example is:

The boy in blue.

Hurry out and fight. In this sentence, dressed in blue is a participle phrase, which is used as an attribute to modify the noun boy. So it mainly depends on which word is modified by the part behind the noun.
