The 5482 is a generic income table for sponsoring other family members. It doesn't apply to parents. None of the parents pages linked to this form, so not sure why you were using it.
The 5772 one is the specific guide to parents. This is the only you should have followed. Plus when you entered the lottery, it very clearly displayed the income required for parents specifically.
Regular EI does not count.
