Can a revolution be considered successful even when certain people are excluded from the revolution?

To a large extent, yes.

Explanation:

Revolutions are not necessarily democratic movements that aim at including everyone in a society. In fact, many revolutions have as a goal to exclude certain groups of people that are deemed to be undesirable or adversary.

For example, the Russian Revolution did not try to include the wealthy landowners and the aristocracy, because they were considered to be the enemey.
