"--Ddraig: "''That Albion. It looks like he’s finally blown away the confusion for the first time in these past two thousand years. Kukuku…then I will also use what has been sealed.''"

From V21, Last.DxD. This confirms that Ddraig and Albion are 2000--"

"finally blown away the confusion for the first time in these past two thousand years" means that it has been 2,000 years since Albion sealed away his [Reduce] ability. And we know that Albion only sealed this ability after meeting Ddraig. This means that it has been 2,000 years since Albion & Ddraig became rivals.

So no. Ddraig & Albion aren't 2,000 years old, they are  over 2,000 years old .
