Is it ok if my 2 year old ate half a crayon ?

I am not a perfect parent so please don’t judge me. My daughter was coloring with her crayons on the table and I am washing dishes and cleaning the kitchen I am the only one home. I look away for 1 second and she was biting the tip of the crayon and it was in her mouth it wasn’t a lot thank god just a little bit I took it away and the box said non toxic I’m a first time mom just trying to keep an eye on her etc but it shouldn’t do that much harm right ?
