Even with newborns, the data says that they are not susceptible like they are with the flu. Some speculation has been that the young are not susceptible to this because they have not developed the receptors that COVID-19 needs to "stick" in the lungs.Yes, the death part you mentioned is correct, but the young kids part is purely speculation/opinion. Not a single piece of tabulated data from reliable sources has stated that young kids are in more danger than the general population.
The data isn't the greatest as there has been less cases, but outside of newborns, which are in the same amount of danger as seniors typically, the little amount of data has said kids as young as toddlers seem to be better off than most.
Maybe you meant newborns, but your original statement is misleading if you meant more than that.
