only care about yourselves

[artart]

1) You only care about yourselves.

Can't that sentence have two meanings:
a) You, as a group, only care about yourselves. You don't care about other groups of people.
b) Each of you cares about himself or herself and no one else.

b) Each of you cares about himself or herself and no one else.

I agree that the sentence is ambiguous and I'd have to rely on context to figure out whether (a) or (b) is intended.
