It is a close race in the sense that either candidate could win, but it doesn't necessarily mean the result will be close. 7 close battleground states mean that either candidate could easily sweep all 7 with a normal polling error.
And yes this includes Arizona, North Carolina, and Georgia. 2 point error is well within a normal polling error.
Polling error tends to be correlated, so most of these states will probably trend in a similar direction. Especially similar states.
