Question regarding ECC

Is it true that ECC encryption may deliver different encrypted results for the same Cleartext/Public-Key combinations although they are always correctly decrypted with the correct Public/Private keypair?

Yes, Elliptic Curve Integrated Encryption Scheme (ECIES) algorithm
generates a random number for encryption.

Thanks for the explanation! A cool feature making things even more secure if I encrypt short information like sex in a database which would be easy to guess if the result is always the same given the same key.
