IMPORTANT NOTE REGARDING THE USE OF THIS GRAMMAR:
Japanese Textbooks may have provided you with this explanation regarding the use of these 2 variants, だ is casual and です is polite. However, this often-taught standard is disregarded in real Japanese everyday life. The focus of だ and です is on the reliance of social space, establishing a personal bubble where only you is inside, while others are outside.
