Essentially, yes.
Pencils contain graphite (pencil lead), which is a type of carbonic rock.
Graphite is used because it forms mollecular layers which easily slide over eachother, allowing the material to easily transfer to the intended medium.
The misconception that pencils contain lead comes from the use of the word alongside pencil in reference to the graphite column. Lead was formerly used for pencils, but was changed to graphite and has remained as such, partially, but not only, due to lead's toxic nature.
