I wonder what does it mean?

doesn't affect me so much

1) That University didn't affect me so much.
2) Coffee doesn't affect me so much.
3) They might want rob me and take my money but as I have no money it won't affect me so much.


I am not sure about the meaning. Does it mean that it won't produce any negative influence over me or not only? I am especially having a hard time understanding the 1st sentence.
