The main reason is simply one of dichotomy: either a substance is pure or it is not pure. If it is not pure then it consists of two (or more) substances which are chemically separate - a mixture.
In this type of classification other situation doesn't exist.
Matter is classified as "mixtures" and "pure substances".

Matter is classified into mixtures based on the physical properties of its components. Mixtures can be homogeneous, where the components are evenly distributed and indistinguishable, such as saltwater, or heterogeneous, where the components are visibly separate, like a salad. Mixtures can also be classified by how easily they can be separated, such as using physical methods for a heterogeneous mixture or chemical methods for a homogeneous mixture.

A solution is considered a homogeneous mixture of two or more substances; solutions are generally liquids but sometimes solid. For gases the term is not so adequate.
yes matter can be both pure substances and mixtures
Its a mixture
A mixture.
A MIXTURE is matter made up of two or more substances that are combined physically, but keep their individual properties.
mixture
This is a mixture.
