[ELI5] In the US, what's the difference between manslaughter and murder? Also, why are there three "degrees" of murder?

if i understand correctly:

1st degree - you plan to kill someone and you kill them (ex: you find out your wife is cheating on you, so you go the store, buy a gun, hide in the bushes somewhere and kill your wife)

2nd degree - you kill someone in the "heat of the moment" (ex: walk in on you wife cheating, so you pull out your gun and shoot her)

3rd degree - manslaughter, you meant to hurt someone but not kill them, but they die anyway (ex: you confront your wife about cheating, slap her, she falls down, hits her head and croaks)
