This statement is true.
A verb in Spanish is indeed reflexive if it ends in -se. If a verb is reflexive, it means that the object of the sentence is the same as the subject. For example: levantarse means to get up, ducharse means to take a bath, acostarse means to lie down, lavarse means to wash yourself, etc.
In English, reflexive verbs are formed by adding pronouns such as myself, yourself, etc.
