There is no magical strategy guide anyone can give you on this front to make you better (believe me, I've looked lol). Reading/Strategy is really one of those fundamental skills (in the same way reflexes, execution, precision, multitasking, etc. are), and fundamental skills are something that you can't gain by being born with them or reading in a book how to do it. You have to build them up overtime and maintain them through practice.
My advice would be don't play with people who are infinitely better than you and can't be touched, but don't play with people you find to be easy mode either. Play with people who you find very difficult but winning is still possible. And try to do so while thinking critically about what you're doing and why during the match. Keep playing and eventually you'll build up those skills.
