I want to become successful

I am a 18 and half yo guy currently in science stream I got essential repeat (failed) class 12th. It happened because of my reel addiction and game addiction too . I have worked on the game addiction but I can’t stop watching reels. I feel very bad and I don’t know what to do. I feel that i can do anything but I don’t know what to do. My dream was to become a chef and leave the country and become successful but after talking to several people I heard that the life of a chef is very hard and the pay is less. So I’ve decided not to pursue my career into this field I have decided to study in bsc biotech.So I want to know will I be get successful by studying biotech. Can I leave india for work and please give me some other carrier options which can make me successful in terms of money
