It works.
But understand what you are doing: you are adding noise to individual's data to make them less identifiable within a specified set of data. The amount of noise you need to add depends on the size of the set they are within.
The OP is also right: For arbitrary customer data (within arbitrary sets of data) you can't guarantee anonymization.
There are also multi-party computation systems, homomorphic encryption and federated learning approaches that all provide different approaches for parts of the private machine learning problem.
It's hard.

One serious problem with that approach is that no matter how well you k-anonymise your data set, someone else's dataset may deanonymise yours.
