You bet.
When water is left in an open container, it can evaporate due to exposure to air. In a closed container, the water vapor will eventually reach equilibrium with the liquid water, leading to increased humidity inside the container. If the container is completely sealed, no water vapor can escape, leading to a buildup of humidity over time.
