Any options trader here who has been successful? Need suggestions.

I am interested in learning options trading but not sure where to start. I have seen a few youtube videos so far but it’s half baked information. There are too many options but it’s tough to pick the right one. Experienced people can guide in the right direction.

I know it’s a risky thing and 9/10 people lose money and all but I want to learn and backtest strategies and see where it goes.

Please suggest where to start and any specific course or channel recommendations would be helpful. Thanks in advance!
