Well the description given by you tells me that you are very much interested in cricket. I also could understand that you are not interested in studies. But unfortunately if you are going to be starting just now to get into cricket it can have its disadvantages like difficulties in earnings which is very essential.
Next Steps
kindly concentrate to stabilise yourself for some small earnings also. Plan some part time jobs if possible so you don't want to depend on or pressurise people. And also practice daily for cricket and live your dream.
Health Tips
Nothing is impossible my friend. 20yrs is not too late for cricket. you can still make it if you are interested. "where there is a will there is a way" But at the same time kindly stabilise your life too or it may be too late. All the very best.
