Groom simply means “manipulate”. It’s manipulating someone verbally, emotionally, or otherwise, to do something for you that they otherwise wouldn’t do. It doesn’t even necessarily have to do with sex.
It’s the same thing with “Molest”. Ask anyone what that word means and 50% of them will have no idea. It just means “annoy” or “harass”. Again, doesn’t have to do with sex necessarily.
What these words have in common is a bad connotation, how the words sound or feel to people. But the denotation (what the word actually means) is completely different.
Diddy enslaved kids. He’s called the Black Epstein for a reason. He didn’t need to groom them or molest them because he flat out owned them. He’s far worse than any buzzwords you could throw at him.
