No, its only the verbs of motion they mentioned in the tips to 4.9 at home 4. They mentioned 10 of them there. There were aller & arriver in 3.21 leisure. And there were 4 more verbs of state in 4.25 life that get être. If you add those up its 16 but its really 15 because they had devenir on the list in 4.9 and also in 4.25. Tomber they get to in set 5. So its those 16 verbs when used intransitively.
You'll find a subset of those verbs can take a cod and when they do, they take avoir in passe compose. But that is a lesson for much later on, like in set 6. But just to show you that concept here is monter conjugated with avoir & etre in passé composé and plus-que-parfait and future anterior:
