First, you are not blowing carbon monoxyde, it is carbon dioxyde.
Carbon monoxyde is extremely toxic.
Second, your lungs capture only a tiny fraction of the oxygen, and your breath has a very small proportion of CO2.
Third, you blowing air on a kindling brings along air as well, it is not only your breath that goes there; you are pushing the air that is between you and the piece of wood to the wood.

Go back to chemistry class. You are exhaling carbon dioxide not carbon monoxide for starters plus there is oxygen with it, granted a lower percentage than normal air, but still present. If it were not present then the fire would not ignite nor would things like mouth-to-mouth cpr be effective.

cuz you are not just blowing carbon dioxide at the fire, it is also moving oxygen to it as well. And if you take in a breath and blow it out immediately then there is still oxygen in that breath.

Because there is still oxygen in the exhalation.

Exhaled breath has more O2 in it than CO2....
