The statement is not necessarily true. Although it is true that if the electric flux through a closed surface is non-zero, there must be an electric field at points on that surface, the converse is not true. A closed surface with zero electric flux could still have an electric field present at points on the surface, but the direction and magnitude of the field could be such that the total flux through the surface is zero.
