Will estrogen change your voice? Almost certainly no.

Can estrogen change voices? Absolutely and it is verified and documented in post-menopausal women who see voice drops and the voice returns to a higher pitch after beginning estrogen therapy.

Does this mean estrogen can change MtF voices? Maybe, but the odds are so low and the likely change is so minimal that you should plan on extensive retraining or VFS (or both).

True,maybe my training as a pro singer will help me haha.I am scared of the surgery,but I will do what I gotta do

With the amount of voice control you have exhibited in that clip I really would not recommend surgery at this early stage, it would greatly constrict your range. I think you will be able to do it easily, I think your first attempt in the clip was nothing short of brilliant.
