No, substances can be elements or compounds. Elements are pure substances made up of only one type of atom, while compounds are made up of two or more different types of atoms chemically bonded together.
All gases are made up of elements, but some are not pure elements. Some are compounds, which are not the same as elements. For example, CO2 is a compound and a gas, but not an element.
