Total number of Chinese students about 370k https://fortune.com/2021/08/16/us-universities-international...

Your link shows: The CSC funds approximately 65,000 Chinese students studying abroad in a given year, and the same number of international students in China.[1]

The vast majority of students from China in western countries pay out of their own pockets, i.e. their parents saved up or their family are wealthy.

Don't get confused with the CSC who mainly give scholarships (tuition, accommodation, stipend) to non Chinese nationals to study in China.
