Problem:
The user was trying to implement a view filter that will compare values as numbers(>= <=, etc.) for a checkboxes field.
Solution:
It won't be possible to search using a comparison on a Checkboxes field. Because the field's values are stored as serialized arrays, and search within them is always performed using a "LIKE" operator. Check the possible operator for custom field search here https://developer.wordpress.org/reference/classes/wp_meta_query/
If you need to use "greater than" operator you will need to use a different field type.
I'll suggest using a select field instead of a checkboxes field. You may also use a number field or a single-line field.
