(1) You shouldn’t judge
someone until you know what they are really like.

(2) You shouldn’t judge
anyone until you know what they are really like.
Is (2) grammatically correct? If so, what's the difference between these two sentences?
I suppose:
(a) The speaker of (1) had one particular person in mind at the time of speaking.
(b) (2) suggests "any person without exception".
My English is probably at CEFR A1 or A2 level.
