Seems like the stuff you listed is marketed to owners who have no clue what they're doing, but are having problems with their animal. Or basically just... people who don't know what they're supposed to be doing.
Ball pythons get everything they need from a diet of rats, and only rats. (Or mice and only mice, for those who refuse rats.) Along with proper humidity and temps and hides, just from having a good enclosure. Nothing else is needed!
Honestly, any additional products past what ball pythons NEED should be seen with skepticism, because the only possible outcomes are either useless or negative.
