No, no, you would choke on CO2. CO2 is the one and only gas you can suffocate on and actually feel it, because checking to see if you are getting rid of your internal CO2 is how your body actually knows it's choking. CO2 isn't actually very harmful directly though, and is only really a concern if there's so much in the air that it displaces the oxygen (see other inert gasses like nitrogen, helium). There is a slight cognitive drop in high concentrations, but generally not any lasting damage even at much higher concentrations than we have.
Currently, there's like less than 1/10th of a percent CO2 in our atmosphere. The best way to limit your "exposure" to it is just to open a window now and then so it doesn't build up if you're inside. Fresh air does actually slightly improve things, it's not just boomer speak.

Starts at about 600ppm, iirc. Office buildings can get into the thousands.🎉
