If so, please could you explain how this happens, is it because as co2 diffuses into the water, it displaces o2?
(sorry for non technical terminology, I am sooooooo no a scientist type chap lol)

No and no, CO2 does not replace O2, it mearly super-saturates, which is why when you provide surface aggitation some CO2 is lost.
There is also another school of thought, by having increased CO2, with a good plant biomass and healthy growth, you will actually achieve a level of O2 in the water that is greater than normal because of the accelerated photosynthesis.. so one could argue, that by adding more CO2, your actually adding to the amounts of O2 held in solution regardless of surface aggitation. My own tests have shown though that no surface aggitation will result in very unhappy fish, very quickly.
