Any time i run this query

SELECT country_name, year, value 
FROM `bigquery- publicdata.world_bank_wdi.indicators_data` as WB_WDI 
WHERE indicator_name = 'Population, total' 
AND year = 2016

I keep getting this error bellow.

Access Denied: Table bigquery-publicdata:world_bank_wdi.indicators_data: User does not have permission to query table bigquery-publicdata:world_bank_wdi.indicators_data, or perhaps it does not exist.

This is a public database, and I looked to make sure the table existed. I am not sure why I am getting the error. Can anybody help?
