Its not easy to enter and exit the body as some people make out to be... thats why the jinns are so reluclant to leave...
More convincing is that fact that jinns can hide in the body to try avoid detection.
But a raqi who is experienced and with the Help of Allah can not only find jinns in the body thats hiding but can tell the difference between jinn and mental illness.
Lets give a simple example... if you and squiggle both wore niqab and pretended to be a woman (sorry squiggle) a person with little experience might not know that squiggle is male, but one who is experienced at determining gender from the body language will know straight away and no fooling them.
Its a basic example but in ruqya its a similar sort of thing but on a more complex scale.
Also squiggle you can learn stuff from books but remember books about ruqya are general and only part or portion of the whole process.
Similarly books about dream interpretaion are ok to read cos they might have general points and examples from hadith but a book cant specifically interpret your dream cos you might have the same dream as another person but your dream means something compleatly different because if your situation. etc
So same thing with ruqya books. people are different and so are jinns some jinns might react to one verse or one thing dont mean every jinn will react in the same way.
ruqya can be a bit complcated, and a lot of it depends on Allah (swt)guiding your heart to saying and doing the right thing.
Allah Knows Best
