yes, and yes. Your 24-word recovery seed (and your optional bip39 passphrase, if you use one) is in fact the root master private key from which all your private keys are calculated.
Anyone one with that seed phrase (and your optional passphrase) has full access to ALL your ledger accounts. So protect this seed phrase well, and NEVER store in on anything electronic, computer, phone, etc, and don’t take any photo of it.
