For living things (animate nouns), grammatical gender usually follows natural gender (e.g., де́вочка — girl → feminine; ма́льчик — boy → masculine).

For things (inanimate nouns), a gender is simply a grammatical property, usually determined by the noun’s ending.
For example, маши́на — car is feminine, while цвето́к — flower is masculine.

Knowing a noun’s gender matters because adjectives, pronouns, and past-tense verbs must agree with it and change form depending on the noun’s role in the sentence.

For most nouns the rule for determining a gender is straightforward.
