How can I learn how to dance? (Hip-Hop, freestyle, etc)?

[I want to be 165 xD]

I am a 16 year old guy who wants to learn how to dance. Thing is there is a dance I would like to learn (a music video) but it's too hard for me to copy or imitate him because it just seems too fast and hard for me to even start. Is it better for me to just copy it or should I learn how to dance from the start? (like learn the basic skills and stuff)? I am pretty good in singing and I don't think I don't have rhythmic skills but I never tried dancing. How are people so good in dancing like popping and waves and hip-hop etc? How did they even start? For me, I think dancing is the hardest thing in the world because I dont know where to even start learning. What should I do? Also, if you get better at dancing, do you learn to dance other dance moves faster and better? Am I just the only one who thinks like dancing is impossible? I think I don't have talent in dancing but who knows since I never gave it a try. (I never dance in proms or parties or whatever cuz I just don't know how to lol) Anyone help me!?
Is dancing like a born-to-do thing? Is it a skill I can't just become good at by effort?
