From Deterministic wallet:
A deterministic wallet is a system of deriving keys from a single starting point known as a seed.
From KDF from Wikipedia:
In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a main key, a password, or a passphrase using a pseudorandom function (which typically uses a cryptographic hash function or block cipher)
Will I be correct to say that deterministic wallets are KDF construction, where the entity from which the secret key is derived is a seed (or word phrase)?
