Technically accurate, but not accurate in any meaningful way in this context.

The planet would be unlivable LONG before CO2 levels got high enough to directly risk the health and safety of humans through inhalation.

We aren’t even halfway to the “this isn’t a great idea to live in” levels, and far from lethal levels. Purely from a “toxicity” level your bedroom at night is far worse than projected co2 levels in the next 100 years.

Does that mean it’s fine to keep increasing? No. But arguing that we are anywhere near “high levels” as it pertains to toxicity is inherently flawed.
