Nah, switch will be luck to cross 100M mark, most likely going to make 3DS numbers, 70-80M.
PS5 and Xbox scarlet are coming, and they are going to steal switch momentum.
Since Switch is a "secondary console" for most in the US ( https://segmentnext.com/2018/08/09/nintendo-switch-secondary-console/ ), when ps5/scarlet arrive sales are going to drop as people starts to buy the "main console" for next generation.
