I think your mother would very much love to fulfill your own dream and not hers. But, if you have the same dream then it gets easier.
Your father is trying to give you an education so you can provide for yourself, I don't think they want you to be responsible for them if ever the time comes that you get successful in life. I mean, that's how parents are.
Now you said you are trading. Are you sure about the path that you are taking? Even though you learned so much about it there are always chances that you might get rekt if the market won't fluctuate the way you like it. There's still risk involved in it and you will need money for your capital which means spending, so where will you get that money?
Don't get me wrong I am not bringing you down, it's just that you said you are still a student and I do believe your father can still manage it for your education. If you can save some money by working a little then good, but don't force it and try to finish that education first. It will be the best gift you can give to them.
This can depend on what country and culture that OP has grown from because if OP came from a culture that always returns the favors and debts they have from their parents or just the culture of giving back to your parents especially if they were good to you and they have raised you well then it's likely that OP won't mind doing just that. I do see your concern too that OP is still a student but I see this as a motivation for OP to try harder in his studies to try, if you're good at school then you can expect that your chances of getting a good job or career will be much higher.
As much as noble this plan is, I say that you should build a foundation of wealth for yourself first before giving it all back to your mother because you don't want to be left destitute after all you've given, make sure you can still live on your own and be able truly independent.
