Traffic and users are different metrics. It's still possible that >50% of users are based in the United States, and account for ~49% of traffic. But without looking into any data, my guess would be that reddit users in the United States make up less than 50% of all users.
The correct word would be plurality.
Precisely this. Their verbiage is wrong, but their point is sound.
I sort of get what they're saying. No other one country contributes more than 48.69%. They just said it wrong, probably.

Both are correct. Not being a majority does not prevent the US from being the largest single nation by Reddit users.
