'Workers vs Jobs' shows total number of workers at given education level and total number of jobs for that education level. So for example number of employed uneducated workers / number of all uneducated workers.
'Employment' shows number how many people has a job (at given education level). Number of jobs in service buildings and in industry areas are together in column 'SRV' (I didn't see any point to separate them).
It works in same way as above mentioned mods but it counts ALL available jobs in your city - that means jobs in all service buildings and also in all industry areas buildings, special buildings etc. This mod is a little bit enhanced version of amazing mods Employment Details and Demographics: Jobs and Employees.
