The only condition is on boss node:

If you get defeat, C rank and D rank (or even E rank wut), you won't get a ship.

If you get victory, B rank and A rank, you will get a ship for sure but ships that are labelled in red colour in the drop table will not appear.

If you get victory, S rank, ships that are labelled in red colour  in the drop table will appear in low chance.

If you mean by the chances of getting a ship in the drop table. Well, I'd say RNG.
