Yes. It should be showing you, in steps, connections away from yourself. As the connections move further back, it should include a lot more people. It may depend on how well connected your tree is. I have managed to connect a lot of people into my tree, lots of second marriages, and marriages of distant cousins, and their families etc.
When I look through your great great grandparents, only the Markle descendant, have descendant created, other than your own line. So by adding as many cousins as possible, then adding spouses of cousins, and adding the parents and siblings of the spouses, will increase the number of people you are connected to.
I have the advantage, or disadvantage, that both of my parents divorced (obviously both) and both remarried, virtually more than doubling the number of lines I have going back, and adding many more connections.
By the way, that would be an indication it is working. You are 0 steps from yourself. Your parents, siblings, spouse and children, are 1 step from you. Your grandparents, uncles and aunties, spouses parents, childrens spouses, childrens children, would all be 2 steps from you. Etc etc.
