Is you daughter growing up in isolation? If not then your conclusions don't really amount to much. Parents normally don't want to hear it, but the influence you have on your kids relative to their own age group is minimal. Perhaps if all of the girls she plays with, and all of the stuff she sees on TV or on the street were different she would be too. But it's *very* difficult to go against "the grain" and their own social group (which they innately detect from a very young age, we are social animals after all) is extremely important.
I always have this story (scientifically totally irrelevant of course) where my neighbours had a young girl of 5 with 3 older brothers who were always playing football and playing catch and such. She'd play with them and she was really good at it! She could throw a really mean ball for such a little girl. Then at 6 she went to primary school and in _months_ she lost all ability to throw or kick a proper ball! When confronted ("what's wrong with you? you used to be good at this!") she answered "but if I throw like this at school the other girls won't play with me!". As a teenager it impacted me at that time, for me it was the first time I saw such an obvious example of how your environment affects you.
So perhaps your daughter would always have preferred the dolls over the train set, who knows, but unless you lock her up and don't let her see the outside world I'm afraid we'll never truly know
