What are the differences between the two queries?

   SELECT     CountryMaster.Id
   FROM       Districts INNER JOIN
   CountryMaster ON Districts.CountryId = CountryMaster.Id

   SELECT     CountryMaster.Id
   FROM       CountryMaster INNER JOIN
   Districts ON Districts.CountryId = CountryMaster.Id

Please mind the i) Table positions and second ii) On Fields

As I know, output will be same. But I want to know, is there any drastic effects of the same if I neglect positions of tables and columns in complex queries or tables having tons of data like thousands and lakhs of rows...
