ELI5: If Helen Keller was born blind and deaf, how on earth did she learn anything?

I don't even really understand how she wasn't a vegetable, since we learn about how to think and reason and communicate through either listening or reading. Yet she turned out to be a genius. How?!

She was actually born with both sight and hearing, but lost it to disease at 19 months.

She learned via touch and by having the words for various things spelled into her palm.

She learned to speak by feeling peoples lips as they talked.
