Quite the opposite. Tanks were a decidedly underwhelming weapon due to the initial use being squandered by the British - though it was part of the push to relieve pressure on Verdun and thus keep France in the war.
The real lesson from tanks is the impression on the German psyche which led to Manstein, Guderian and Rommel, the concept of Blitzkreig and the fall of France in 1940. Post war tank warfare on the allied side was (generally) very staid comapred to German thinking. Though there were some good thinkers, included Liddell-Hart who showed you could take tanks through the Ardennes...
WW1 ended because Germany exhausted herself utterly in the failed Spring offensive of 1918. The UK's blockade of Germany was having horrific consequences on the home front. Meanwhile the advances that were made in Spring 1918 by Germans led to them capturing lots of supplies from the newly entered USA, thus undermining their morale further.
