    Try this measure out 

    SelectedCount = 
VAR SelectedID = SELECTEDVALUE(Table3[id])
VAR FilteredCodes = 
    CALCULATETABLE(
        VALUES(Table2[code]),
        Table2[id] = SelectedID
    )
RETURN
    CALCULATE(
        COUNTROWS(Table1),
        Table1[code] IN FilteredCodes
    )

      Thanks for a quick respond! When tried your solution it took loong time and got a message "Couldn't load the data for this visual". Table1 has more than 10 mln records and I have filters for visuals on the page. May be I need to add filters to the measure also? If you can add to your solution for table1 source_id = 1 and service_id = 2 ? Many thanks!

        I tried to refactor the DAX 

        SelectedCount = 
VAR SelectedID = SELECTEDVALUE(Table3[id])
RETURN
    CALCULATE(
        COUNTROWS(Table1),
        FILTER(
            Table1,
            Table1[code] IN 
            CALCULATETABLE(
                VALUES(Table2[code]),
                Table2[id] = SelectedID
            )
        )
    )
