Obviously YES, we call a certain thing as living things if it has life while non-living things if they don't. The other term for the term 'living thing' is 'biotic factor'. We can't call a certain thing as living things if they don't live.
Remember:
living things live while non-living things don't.
Examples for living things;
Plants
Human
Animals
Fungi
Bacteria; etc.
Hope it Helps =)
