Ranking will depend on what type of results functionality your department uses in eVision for your paper.
If a paper uses Results 1 functionality you will only see your final result which will not be ranked.
Results 2 functionality will show the results for each individual item of assessment and your student ranking which is available to both you and staff.
Once a result is finalised (i.e. when the final exam result is added) the rankings will not be visible for you but continue to be available for staff.
