YouTube Data API results differ from YouTube search bar results

I was trying out the YouTube Data API and after trying different query searches I found out that especially with filters the API returns different results than my YouTube Data API. Is there a reason for that?

For example I tried to get the most viewed Videos with the query string "Cooking":

    try:        response = service.search().list(            part='snippet',            type='video',            order='viewCount',            q='Cooking',            maxResults=10        ).execute()

it seems to return Videos with high view counts but nothing close to the view counts I get when I type "Cooking" in the YouTube search bar with the filters "video" and sort by "view count". Can someone explain how to fix it or why it doesn't work?
