For sure. Many Americans are confused by percentages. They do not understand that 20% is equivalent to saying "in a room of 100 people, 20 of them are trans", and even if they did understand that, they wouldn't have the proactive reasoning to make sure their percentage estimates add up/overlap in a way that makes sense, e.g not implying that 20 people in the room are all Hispanic Asian atheist Catholic bisexual transgender millionaires.
