Mastodon doesn't claim to be and is transparent about it. Evil instance admins could extract your DMs from the database and therefore are technically able to read them.
The same fact is true for most messengers, email, SMS, Twitter, Google Hangouts, Skype, Riot, IRC…
Private and confidential conversations require a platform with *mandatory end-to-end encryption*. Social media and most messengers are technically incapable to protect your privacy.
