Hi,
" I do" as an answer means 我願意.<---------------- You are right, but
that's not all.
When you say " I do", it does NOT ONLY mean you 願意.
Examples for you:
1) A: Do you love me?
B: Yes, I do. <------------(B means B loves A)
2) A: Do you understand my explanation?
B: Yes, I do. <---------------( B understands what A says.)
In a word, it depends on what types of questions you have to answer.
