Yes, odorants need to be volatile in order to be smelled. This means that they must have the ability to evaporate into the air so that they can be detected by the olfactory receptors in the nose. Non-volatile substances cannot reach the olfactory receptors and therefore cannot be smelled.
would water be one because it has no smell and it evaporates at normal temperatures??
==========
As illustrated by the first answer - yes. Our noses don't detect ALL gases as smells and if we can't smell it it, by definition, doesn't have an odor. That is not to say it can't be detected in the gas phase, just that our noses can't do it.
Volatile substances are carbon based chemicals that easily evaporate at room temperatures. As it evaporate mostly volatile substances have odor.
Of course. The Human nose cannot detect every scent, and there are far too many compounds that we can't smell everyone.
"Volatile liquid" simply means that it evaporates easily. Some such liquids may have a pleasant smell, others may have an unpleasant smell, others may not smell at all.

What things must happen in order that a substance can be smelled?
For a substance to be smelled, volatile molecules must evaporate from the substance and travel to the nose. These molecules then bind to olfactory receptors in the nose, sending signals to the brain which are interpreted as different smells.
Is perfume a form of a gas?
Perfume and cologne are liquids in a closed bottle. When sprayed, it breaks into small droplets of liquid as it travels through the air. At this point it is a liquid and cannot be smelled. Rubbing the perfume into the skin causes the skin to absorb the liquid. Because the perfume is volatile, the liquid then slowly evaporates. At this point it is a gas and can be smelled. Note that some of the liquid quickly evaporates to gas during the spray, which can be smelled.
