No. `Languages` is interpreted as *alias* to table `Country`:
SELECT ... FROM Country Languages
is same as
SELECT ... FROM [Country] AS [Languages]
And
SELECT ... FROM Country Official
is same as
SELECT ... FROM [Country] AS [Official]
And that's why `SELECT ... FROM Country Languages` return exactly same result as
`SELECT FROM Country Official`; if you would've issued just `SELECT ... FROM
Country`, it would've returned same result as well.
