Reverse geocode through Google Maps API inaccurate?

Question

I have placed around a 1000 markers in my area through Google My Maps, transformed the KML file to CSV, and now want to transform the coordinates to addresses. I am just testing with the first 5 to test my script (Python) but I am finding that from the 5 test records, only 1 is correct.

For example: 
Coordinate: -33.7909042,151.2603029
Google map: http://maps.google.com/maps?force=canvas&t=m&q=loc:-33.7909042+151.2603029

Clearly you can see the address is Rickard St 42

BUT
When you use the API to geocode the coordinates with: 
https://maps.googleapis.com/maps/api/geocode/json?latlng=-33.7909042,151.2603029&key=APIKEY

It returns 119 West Street, on the opposite side.

I thought the Google Maps API was really accurate, but the service doesn't reflect the actual map itself. What is going wrong? Is there a better service?

I can confirm that using google the map gets across in to the wrong address.

Google maps are very good in what they do, but like everything else, sometimes technology fails. I presume their AI that transformed the map marker location got it right by artificially moving the target, where the API did not.
I used same input with out reverse geocoding tool CSV2GEO  and we got the results right on target.

Here is the result from the reverse geocoding
