It isn't that the number is literally relevant. The point is that neither the deficit as an absolute number, nor the GDP as an absolute number, is terribly meaningful -- they both need to be contextualized. To do this, you can compare them to one another, and look at relative changes.
A crude example: spending $100 a month on a cell phone with a good data plan is a big deal if you're 16 and work part-time at McDonalds; if you're an investment banker pulling in 6 figures a year, it's a fairly minor expense. You can represent this in general by looking at an expenditure as a percentage of annual income.
