In Israel the % of practicing Jews is 19%.
I don’t know where you ever got those numbers, but it is incorrect. The majority of Jews who are, as you say “practicing” is far, far greater than 19%.
There are a number of sects in Judaism. Each with their own traditions and levels of Torah observance. The “Ultra-Orthodox”, in Israel are among the fastest growing in the population, just by birthrates alone. Most of the nation, approximately 75 % of the Jews, is comprised of Sephardim, and they are Orthodox Jews.
