I think you shouldn't include the query parameters in the URL. Try simply using this when creating the ServiceFeatureTable.
https://services3.arcgis.com/df7XtT0Re4z8S561/arcgis/rest/services/redlist_species_data_7b024e64_0fd8_48a2_adf0_8e43737b5cb3/FeatureServer/0
Note, you can call loadAsync on the ServiceFeatureTable and see if there's a loadError to help home in on the cause of issues like this. All Runtime classes that work with remote resources will implement the Loadable pattern. See this page for more details.
Hope that helps.
