No, these proverbs have different meaning. They’re not the same.
“Bèf bout ke se Bondye ki pouse mouch pou li” means something like God helps people that have deficiencies or limitations.
The second proverb “Se mèt kò ki veye kò” means You watch out for own self. Don’t expect others to care for your well being. This proverb is in the same category as another Haitian Creole proverb Chak koukouy klere pou je yo Each person looks out for his own interest
