'der Durchschnitt' and 'das Mean' can both refer to the same calculated value: you add several numbers and divide by how many there are. The important difference is in usage. 'Durchschnitt' is the normal German word and fits in school, everyday life, and many professional situations. 'Mean' is a technical term from statistics and often sounds unnatural or very technical in everyday German sentences. Learners may confuse the words because both can refer to the same value. As a practical rule: in normal German, you almost always say 'Durchschnitt'; 'Mean' is more appropriate in statistics, data analysis, or academic texts.
