No energy is gained. On the contrary, energy is required to make ice melt.
A calorimeter is typically used to measure the energy gained or lost when sunlight is absorbed by a tank of water. This device can measure the changes in temperature of the water to calculate the energy transferred.
Condensation is exothermic. Energy is released during condensation. Energy can not be "lost" but merely change from one form to another.
The energy released when 6 grams of water is condensed from water vapor is equal to the heat of vaporization of water. This is approximately 2260 joules per gram. So, for 6 grams of water, the total energy released would be around 13,560 joules.
When 2 grams of water is converted from liquid to gas at its boiling point, it requires an input of approximately 2260 joules of energy. Conversely, when 2 grams of steam condenses into liquid water, it releases around 2260 joules of energy.
It should be noted that energy cannot be gained or lost due to energy conservation. But there is a bit more to this as regards the situation being asked about. In terms of the energy of the water vapor, yes, the water vapor has more energy after it has evaporated. It has to have to have evaporated. The water vapor leaves the water from which it came with less energy; it took energy with it to evaporate. Either way, energy has been transferred from the body of water to the water that is evaporating, and it might help to view what is happening in that light.

Energy is used when water changes from a solid to a liquid.
You get steam because the molecules have gained energy in the form of heat and are moving faster and further apart which also increases pressure if you try to contain it. It takes in energy

Energy is gained during evaporation because it requires heat energy to convert liquid water into water vapor. This heat energy breaks the intermolecular bonds in the liquid water molecules, allowing them to escape into the air as vapor.
When water has heat and energy it changes energy. The energy that it changes to is called thermal.
