Clickworker Tax

I was linking my PayPal account then the last question was this " I am commercial and / or freelance " and I just ticked "no", now I am worried that they need a tax number in order to pay you. I am still a student so there's no way that I have a tax number. My question is that, will they still pay me?

Sorry for my English as it was not my primary language.

It would be great if someone would clarify this for me. Thanks.
