RETURN apoc.coll.containsAll(mainList, sublist) AS output;

Cypher’s any()

WITH [1,2,3,4,5] AS mainList, [3,7] AS sublist
RETURN all (x IN sublist WHERE x IN mainList)

Results
Output
false

WITH [1,2,3,4,5] AS mainList, [1,3] AS sublist
RETURN all(x IN sublist WHERE x IN mainList)

Results
Output
true
