My daughter has completed M.Sc in biotechnology in 2021, she is pursuing Medical coding to get job with 40k at the begining in MN C. Is it correct decision to enter medical coding.

Dear Sir, I did my BTech from a normal engineering college not very famous. The teaching was not great and hence i did not study well. I tried my best to learn coding including all the technologies like html,css,javascript,react js,dba,php because i wanted to be a web developer But nothing seem to enter my head except html and css. I don't understand a language which has more complexities. Is it because of my lack of experience or not devoting enough time. I am not sure. I did many courses online and tried to do diplomas also abroad which i passed somehow. I recently joined android development course because i like apps but the teaching was so fast that i could not memorize anything. There was no time to even take notes down. During the course i did assignments and understood the code because i have to pass but after the course is over i tend to forget everything. I attempted a lot of interviews. Some of them i even got but could not perform well so they let me go. Now due to the AI booming and job markets in a bad shape i am re-thinking whether to keep studying or whether its just time waste. Since 3 years i am doing labour type of jobs which does not yield anything to me for survival and to pay my expenses. I have the quest to learn everything but as soon as i sit in front of the computer i listen to music or read something else. What should i do to stay more focused? What should i do to make myself believe confident. Is there still scope of IT in todays world? Kindly advise.
