Hello, @Ashish Malik ! The Azure credits will pay for the VM you put your OS/software on and you can use free marketplace offers, however you cannot use Azure credit as payment to Skytap. I'll go into more detail below.
Are Azure Marketplace offers included in the $200 Azure credit?
No, your credit can’t be applied to Azure Marketplace offers. However, many Azure Marketplace partners offer free trials and/or free tier plans for their solutions. You can only purchase products on the Azure Marketplace once you've moved to pay-as-you-go pricing:

What this means is that Azure services are included (like Virtual Machines) and operating systems like Windows 11 have been made available free for dev and test scenarios for Azure free trial subscriptions, however you cannot use Azure credit for marketplace offers.
