Most gambling sites usually has 1 confirmation to show the balance and 1 confirmation to withdraw.

Blockchain.info API V2? Based on their documentation, you can request Blockchain.info to send the callback immediately on receiving the transaction. You can implement the system to only acknowledge the callback when it has at least 1 confirmation. It isn't that hard to do.

Yes and please NEVER allow for 0 confirmation on online services, they are extremely vulnerable to double spends.

When a payment is received, blockchain.info will notify the callback URL you specify. Please note, the callback url is limited to 255 characters in length.

transaction_hash - The payment transaction hash.
address - The destination bitcoin address (part of your xPub account).
confirmations - The number of confirmations of this transaction.
value - The value of the payment received (in satoshi, so divide by 100,000,000 to get the value in BTC).
{custom parameter} - Any parameters included in the callback URL will be passed back to the callback URL in the notification. You can use this functionality to include parameters in your callback URL like invoice_id or customer_id to track which payments are associated with which of your customers.
