Answer:
It is "significant" because it was the largest naval battle consisting of battleships and battlecruisers; over 250 warships. It wasn't the largest naval battle, "Leyte Gulf" in WWII was the largest. Nor was it decisive, "Jutland's" nick-name is the "Battle of Lost Opportunities."
Thats where your wrong it was very decisive in WW1, first and foremost the German fleet never came out of German ports again for the remainder of the war, therefore giving the Royal navy supremacy of the seas.
2. Royal Navy continued blockading Germany right till the very end of the war refusing to come out again like Jutland, so it was very significant for the final victory.
