Since Trump's election, gun groups catering to progressives and people of color report a surge in interest as they look to defend themselves in a country that, to them, feels increasingly unstable.
In the United States, drowning is currently a leading cause of death in children aged 1- 4 and the second leading cause of death for children between the ages of 5-14.1 There are over 4,000 fatal drownings occurring each year in the US.
They lump all gun deaths 1 to 19 into that bucket, which skews the numbers heavily. It's literally the same shit right wing groups do to fuck with the numbers and make them look bad. Anti-gun groups do this specifically to make it seem like toddlers are being killed in droves. When in reality it's gang violence from the top end of that age range. Which is an issue, but it's not a gun issue, it's a education, safety nets, jobs issue.
