The above statement is true.
Non-metals are not good conductors of electricity because they do not contain free electrons. Each carbon atom in graphite is bonded to three other carbon atoms, resulting in a free electron. Graphite is a good conductor of electricity because of the presence of this single delocalised electron. Graphite is a good heat and electricity conductor.
