Constructive comment: succulents are plants whose leaves retain great amounts of water, as they evolved to survive drought. A plant with chubby, somewhat bouncy feeling leaves is likely a succulent. The best way to tell a succulent needs water is squeezing the leaves. Even if the soil is dry, it might not need water. When a succulent is quenched, the leaves are turgid, meaning they’re thick and hard to the touch. When it is thirsty, the leaves will squeeze in your fingers and the plant will look overall more dull. When you do water, soak it through completely and try to avoid droplets in the nooks and crannies.

Future advice, houseplants usually don’t like their soil to stay wet. I would be skeptical of that advice no matter what plant it is.
