DuckDucGo's classic link results are verbatim from Bing (or sometimes Yandex instead). DuckDuckBot is only used to grab favicons and a subset of its rich results (instant answers, zero-click info). Don't take my word for it; you can compare DDG and Bing results for esoteric queries side-by-side. The order of the results may vary since search results aren't deterministic, but you'll find them to be otherwise identical. You can also ask staff in help channels about the details of where link results are sourced from.
