Affiliate Marketing Secrets

I’m 17 and I have a website which generates a good income from affiliate marketing. I’ve closely read ToS of the programs I am using and they do not specify that I need to be 18. I’ve also contacted my bank and they told me that my bank account is under my name only and my parents do not have access to it. I use prepaid visa gift cards to pay for the website hosting.
Should I tell my parents about this income? Do I even have to tell them?
