The answers above are examples of why the statement is false for a pure chemical compound (such as pure water, H2O having a set number of atoms per molecule). The number of atoms will always be greater than the number of molecules of such subatances.
Substance can refer to things other than pure chemical compounds. If Hydrogen plasma is a substance, then pure Hydrogen plasma contains exactly the same number of atoms as the number of "molecules." The same might be said of any pure metallic element.
One mole of pure Iron contains one mole of Iron atoms (one gram molecular mass of Iron contains Avagadro's number of Iron atoms).
The statement is still false, because it is not always true.

Substance could be compounds like water, H2O, one mole of water actually has 2 moles of hydrogen and 1 mole of oxygen

one mole of water (chemical formula H2O) has 3 moles of atoms.
