the main reason is condensation of water vapour in the air to water droplets
yes.
The outside of the cup is warmer drawing in condensation from the air and your drink.
The water on the outside of the cup is an example of condensation.
Condensation
this is called condensation in the water cycle it forms water droplet because when the liquid turns into gas the particles move and when they spread apart and float away some get stuck on the sides of the glass cup. Then with enough of the gas particles come together turning it into droplets and goes back into water to do it all over again.
Condensation and Dew are related because Dew is practically Condensation since Condensation is Gas to a liquid. Humid turns to liquid. For example a cold glass of water that is outside for a long time. When you come back out you will see droplets on the side of the cup.

Condensation can only occur on a glass that is cold. The reason why condensation forms is because water vapor in the air (a gas) cools and turns into liquid water when it comes into contact with a cold surface.
Assuming the glass cup held a cold liquid, the air closest to the cup will be colder than the surrounding air, causing water vapour in the air to condense into liquid water droplets.
a condensation of water will form on the outside of the metal container. What really happens is the frigid temperature of the cup actually cool the air down that it comes in contact with and water droplets form.
This is called "condensation" on a glass, and "dew" if it occurs on grass / leaves. When the "dew point" of air is above the temperature of the surface of the glass, condensation will occur as humidity from the air releases heat into the glass and changes state from gas to liquid.
