This 100%. If someone tells you that they are nice or too nice, they use their niceness to try to get things from people. Truly nice people do not go around telling others that they are nice. They just are nice.

That said, calling someone else "too nice" or saying that someone is "nice" can interchangeably mean that they are just naive.
