GQL isn't really much like a graphdb (e.g. SPARQL).

The goal of GQL is to gather a useful subset of your microservice data into a single tree for your frontend to render. In a facebook context, a typical query is "give me all the info i need to be able to show my home feed".

The goal of graph dbs is to allow arbitrary, complexm, often cyclic and aggregating queries to be run against a data source expressed as a graph. A typical query is something like "how many of my friend-of-friends like basketball, displayed by location."
