Is it correct that a stream cipher using a truly random key binary sequence is the unbreakable One-Time Pad cipher?

A stream cipher is a type of encryption algorithm that operates on individual bits or bytes of plaintext and produces a corresponding stream of ciphertext. It is based on the use of a key stream, which is generated by combining a secret key with a random or pseudorandom sequence of bits. The key stream is
