as I was told from early education that the air we currently breathe in contains 21% oxygen and 77-ish% of nitrogen and the rest are other particles.
So I have a dumb question on what the body uses nitrogen we breathe in for?

Nothing for our breathing, it just gets sent back out when we breathe out.
Plants and fungi use the nitrogen as part of their energy gaining process, which is why the Earth’s atmosphere needs it.
