good person vs. good people

Hi,

Do these sentences mean the exact same thing:

  1. She’s good people.
  2. She’s a good person.

I’m not sure about whether #1 sounds natural though, could you advise me on that too please?

Thanks in advance.

I think that #1 is incorrect, because ‘people’ is plural.

I think #1 is OK too because ‘She’s good people’ means ‘She’s (one of the) good people’ which also equals to ‘She’s a good person’. But that’s just my opinion and isn’t necessarily be true. What say you?
