Then why is the XBOX gift card from the microsoft rewards 23000 points and Microsoft store card is 23900 points? What is the difference between those?

If you have enough Microsoft reward points, then you need to redeem the reward points for Xbox/Microsoft Gift Cards on the redeem page of Microsoft rewards. Then once the gift card codes have been emailed to you, then you can redeem those gift card codes on https://account.microsoft.com/billing/redeem Once you have enough money from the Xbox Gift Cards, you can then purchase Minecraft from the Microsoft Store or Xbox Store (depending on which version you want).

If you redeem your Microsoft Rewards points for a $5 Xbox Gift card. You receive $5 on your Microsoft account. You do not receive a physical gift card.

Microsoft Points cards work the exact same way as Xbox Live Gift Cards. A 1400 Points card bought for $20 will put $20 in your Microsoft Account for example.

What happens to Microsoft Points cards?

Microsoft Points cards you purchase in retail stores will continue to be redeemable on your console and Xbox.com until further notice. Microsoft has no plans to discontinue acceptance of previously purchased Microsoft Points cards and codes. Xbox gift cards
will be available for purchase in retail stores and through online retailers starting in late 2013. Availability of Microsoft Points cards varies by region.
