Have a look at Wikipedia -- there can be a small group of people who are the dictators, doesn't have to be just one:
"A dictatorship is an autocratic form of government which is characterized by a leader, or a group of leaders, who hold governmental powers with few to no limitations."
Except the leader is not a group of leaders. It is just one leader. And he answers the council who can vote to remove him. This is far from a dictatorship
