Yeah, atheists just don't believe in a higher power. However, according to your definition, they wouldn't believe in love, anger, or any other emotion which is just not true. I would consider free will to be more associated with human emotion than something like god, so it wouldn't be contadictory for atheists to believe in free will... in fact, atheists would be more inclined to believe in free will since they don't have 'fate' to blame.
