In fact, I´m 24 years old.

I like to play video games,; flying drones, L; learning new things,; and studying software, Hhardware, Eengineering, Tand technology.

Because "study software, hardware, engineering, and technology" is a list of things you study, but this list is inside a bigger list (things you like to do), the items in the bigger list are separated with semicolons instead of commas.

I wannat to meet successful persons etcople.

"Wanna" is ok but is only used in very informal text (like a message between friends).
"Etc." is only used when there are at least 2 items in the list. Because there is only 1 item here, it should not be used.

"In fact" doesn't make sense here, because there has been no argument otherwise. You could say something else to emphasize your age, but I don't think it's needed.
