Could it be a lie? If it could be a lie, it’s a factual statement. Therefore, “I’m hungry” is a factual statement. I could be lying; I could say I’m hungry when in fact I just had a huge meal and am not hungry.
“The sunset is beautiful” could not be a lie, however. There is no truth value about a sunset and beauty. It’s an opinion statement.
Oddly, “I believe the sunset is beautiful” is a factual statement. I could be lying. I could say the sunset is beautiful, when I don’t believe it’s beautiful at all.
