Generally speaking, yes but ...
It depends on what the substance is and what you want to separate.
If the substance is a mixture of sugar and water then the water can be evaporated off and the sugar remains behind.
Water, H2O, itself is not a mixture but a pure substance and it, too, can be separated into hydrogen and oxygen by running an electrical current through it to break the bonds in the molecules.
Some substances like paint can have its components forensically determined by running a sample through a gas chromatographwhich will analyse the components of the paint to determine which brand it is which batch it came from and maybe help solve a crime. The gas chromatograph is used for small samples and does not separate larger samples back into its components.

Are there more pure substances or mixtures found in the world?

Substance that can't be separated?
An example of a substance that cannot be separated into simpler substances by physical or chemical means is an element like gold or oxygen. Elements are made up of only one type of atom, so they cannot be broken down further by ordinary methods.
Is white sugar a mixture or a substance?
Table sugar is a pure substance. It is made up of one type of molecule that cannot be separated into two or more components. Mixtures can be separated. For example, a mixture of water and sand can be separated into two components. Other examples of pure substances are diamonds, and table salt.

How is a substance different from an element?
There are two types of substances: elements and compunds. Elements cannot be separated into simpler substances while compunds can. Take for example iron, pure iron is made of iron atoms, and they can't be divided into simpler substances, as such, iron is an element. On the other hand, salt is a substance that CAN be separated into sodium and chloride, so salt is a compound (and since sodium and chloride can't be furtherly separated they are elements). So, an element IS a substance, but not all substances are elements.
Is mixture a substance?

A substance is when two or more compounds or elements are combined chemically into fixed proportions but can only be separated chemically.
Is homogeneous mixture a pure substance?
No, a homogeneous mixture is not a pure substance. A homogeneous mixture is composed of two or more substances that are physically combined and can be separated through physical processes, while a pure substance is made up of only one type of particle and cannot be separated into other substances by physical means.
Which type of substance can only be separated by a chemical reaction?
A compound can only be separated into its constituent elements by a chemical reaction. In a chemical reaction, the bonds holding the atoms in the compound together are broken, resulting in the formation of new substances.
