How can I start weightlifting at the gym?

So I go to a gym. I usually just do cardio there but I want to weight lift. Wherever the weightlifting equipment are, there are always huge, shredded guys who seem like they've been doing this for a while. I'm 14, and I'm scared to go down because I'm not really experienced with weightlifting and I've never seen a kid doing it in that gym before. I don't want to be the only kid there. What should I do?|||2 of my friends cort and Dylan is 19 and 18 years old and started weightlifting at ur age so it is pretty normal to get interested into that at the age of 14|||talk to the staff so they can help
