Your table is in a proper structure for calculation. But it is not clear which courses have been completed. Does this table only record completed courses by all people? Are "Green Belt Course" and "Green Belt Certified" the same course?
Once these problems are clear, you can then create measures to make the calculations you want. You can add different filtering conditions to measures. For example,
Number of Persons = DISTINCTCOUNT ('Table'[Person])
Number of Persons having Yellow Belt = CALCULATE(DISTINCTCOUNT ( 'Table'[Person] ),'Table'[Training] = "Yellow Belt")
Add measures to appropriate visuals to display the results.
