Does meta only have product analytics?

I have been told that all meta data scientists are all product analysts meaning that they do ab tests and sql.

Despite this, i ve been told by friends of mine that google, amazon, uber… they all have two different types of data scientist: one doing product analytics and one doing statistical modeling and/or ml for business problems.

Does this apply to meta too? I remember looking at their jobs page a few months ago and they had multiple data science roles that had ml as requirement and many more technical requirements, compared to PDS who only have one requirement which is sql.
