Inodes and disc usage still the same

I removed all installations on my domain cus something went wrong with my theme and site stopped responding. But the disc usage and inode usage is still the same as when i had the installations. How can i bring them down to 0?

If you deleted all contents already, you just need to wait a few hours for the inodes to be recounted and the counter to update. The counter is not a live statistic, it doesn’t immediately update with every file change on your account. The inodes are counted every so often.
