3 marks of existence

Is this person describing the 3 marks of existence in the right way. What the Buddha showed was that the actual reality of “this world” is described by the three characteristics of anicca, dukkha, anatta: No matter how hard we try, we cannot maintain things to our satisfaction in the long term (anicca), thus we get distraught (dukkha), and thus we are not in control (anatta).
