Indeed. For comparison: atoms are about four orders of magnitude larger than atomic nuclei. The size of the former is generally a few tens to low hundreds of picometers (1 pm = 1e-12 m) while the size of the latter is just a few femtometers (1 fm = 1e-15 m).
See, e.g. https://en.wikipedia.org/wiki/Atomic_nucleus https://en.wikipedia.org/wiki/Atomic_nucleus for concrete example sizes.
