Is Mautic sending to unsubscribers?

I’m having hard time figure out if Mautic still sends emails to users who have unsubscribed.

If at some point the user unsubscribes, all email sending activity to him are stooped?

Even if there are some scheduled email sending to him?

For example, if i create a segment which is set to gather all unsubscribers in the database, the result is 0.
No contacts, even i see them in the list as i navigate in it.
