"Thousands"????

From The Daily Mail:

World’s largest container ship at 396m long arrives in Britain on maiden call carrying thousands of Christmas presents

•Marco Polo, the new giant of the waves, is five times bigger than an Airbus A380 or the size of four football pitches
•Can carry more than 16,000 containers on board.

Surely there are probably "thousands" of Xmas presents in each individual container? So shouldn't that be "millions of Xmas presents"?? Or possibly even "billions of Xmas presents", if the things are small enough.
