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.
Well, darling, those droplets form because of condensation. When warm, moist air comes into contact with a cold surface like a glass cup, it loses heat and can't hold onto all that moisture, so it forms those cute little droplets. It's like the glass is saying, "Sorry, can't handle all your hot air, so I'm just gonna sweat it out."
The water on the outside of the cup is an example of condensation.
Condensation
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.
Well, honey, those water droplets form on the outside of a glass of water because of condensation. When warm, moist air comes into contact with the cold surface of the glass, it cools down and can't hold onto all that moisture, so it turns into liquid droplets. It's just science doing its thing, no need to overcomplicate it.
If ice forms on the outside of the glass, it is likely due to condensation from the air coming into contact with the cold surface of the glass. This can happen when the drink inside the glass is colder than the surrounding air temperature. It is a natural occurrence and can be prevented by using an insulated glass or coaster.
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.
