Most people certainly do not meet all of the criteria you list, especially #2 ("Markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day."). I can understand some confusion over #4 ("A slowing down of thought and a reduction of physical movement (observable by others, not merely subjective feelings of restlessness or being slowed down)."), which can be read as describing ordinary fatigue but is actually about a different pattern called "psychomotor retardation" [1].
