No.
You have to learn certain courses in the first year, in the second year you can specialise into pure and applied if you want, although you can choose to just study lots of courses.
By the third year you're free to choose from whatever's on offer.
Specialising too early is a terrible idea, you'd have a very poor background in general areas of maths, courses like mathematical methods may not seem relevant to your interest at the time, but a lot of stuff pops up in unexpected places.
Don't worry though, you probably wouldn't have been accepted.
