is debit card and atm card is same

No, a debit card and an ATM card are not the same, although they are frequently issued together as an ATM-cum-debit card, leading to confusion.

• An ATM card is a card with limited utility, primarily designed for cash withdrawals and balance inquiries at an Automated Teller Machine (ATM).
• A debit card is a multi-functional card that can be used for ATM transactions, such as withdrawing cash, and also for making payments directly at retail stores and for secure online transactions.

A debit card essentially offers the full functionality of an ATM card plus the ability to make purchases.
