Suppose we have two transformers with same turns ratio, N_2/N_1. First transformer A is of 100:10 and the second transformer B is 1000:100. Both have same turns ratio so both can step down the voltage by 10 times theoretically. If we assume size of wires are identical at primary and secondary, current and power ratings are same (I am not sure). But eventhough turns ratio is the same for both transformers, the number of turns is different in primary and secondary.

So my question is does the number of turns matter in turns ratio matter? I have a feeling that B has some advantages. But I am unable to figure out.
