The numbers are irrelevant - any shot within the shaded areas aimed about parallel with the numbered boundary lines goes to the corner pocket marked with the red arrow.Is the idea that the 1 and 2 in that first pic go in the pocket with the arrow?
Of course the "lanes" change from table to table - I have to play them a little longer on my usual table, and maybe a little shorter on new cloth. I think the important thing is to learn the shaded areas where "the bank is open" and to recognize that whatever angle works for one shot within that area, shots near it will work with a nearly parallel angle.
