Does ventilation help condensation?

In most cases, internal condensation issues occur because of too much humidity in the room or little to no air circulation. ... The cures for condensation are heating (to keep surfaces above dew point temperature) and ventilation (to expel the warm, moisture-laden air to the outside). Some damp is caused by condensation.

This is the key to why ventilation can help prevent condensation. warm, damp room air goes out of the window and cold air comes in from outside.
