Hi Dương, You could not compare the download_criteria_report_as_string_with_selector <https://developers.google.com/adwords/api/docs/samples/python/reporting#download-criteria-performance-report-as-a-string> example and the get_campaigns <https://developers.google.com/adwords/api/docs/samples/python/basic-operations#get-campaigns> example as both returns different sets of data.
The Criteria Performance Report <https://developers.google.com/adwords/api/docs/appendix/reports/criteria-performance-report> returns data that is being aggregated on *ad group criteria level*, one row per ad group and criteria combination. While for get_campaigns example, it returns all campaigns in your account, meaning, the data being returned is on a *campaign level*. If you want to get the campaigns via a report, then use the Campaign Performance Report <https://developers.google.com/adwords/api/docs/appendix/reports/campaign-performance-report> instead.
