No amount of reading could make you get good, just like no amount of theory crafting could make you successful in an RPG dungeon run, or like how a scientist could never get a body builder body with just trying to study theories and best ways. Practice makes perfect, and well, with that also comes your money. You can try playing without money involved, but the experience that comes with that seems like it would end up null, since the thrill and all also helps in decision making at times. Since you're playing online and not offline, facial expressions could basically be left out, but bluffing could still be useful. Try to craft theories always on what the cards of others are depending on the situation and especially watch out for bluffs.
If you are able to perfectly execute what you read you may actually be a better player. But that's definitely not the only road toward becoming a good poker player. Some earned their poker skills from years and years of playing. Some simply seem to have the knack of it.
Playing without money involved may teach you the basics but not really prepare you for the real poker table. Your hand won't shake if you are playing with play money even if you raise $10,000 but when the real game comes, well, at least from experience, your hand will involuntarily shake when calling even a much much lower raise.
