Bootcamp

So i have a MacBook Pro 16 inch. I set up bootcamp with 150 gb. It was correct when in windows. I needed more space so i used this tutorial https://youtu.be/-WRkeL1Lnq8 it worked but in windows it says i only have 233 gb in bootcamp when Mac OS says i have 250. In the mini tool partition software in the tutorial says i have less storage on both partitions my Mac OS and my windows. Help?
