Doing it that way, would I have to tell it which table? or does it already know?

No need to specify the table. LAST_INSERT_ID() returns the ID of the last insert made on a table with an auto-increment column by the session calling the function.

could that not get something else from someone else?

No because the function only returns the information from the current session.
