Planets can be formed from nebular gases and dusts around a protostar or from the cooling of small stars.

In our solar system all the planets (and Sun) formed from one collapsing nebular. Therefore all the planets have the same stuff inside them. The differences between planets is caused by the differences in their outer layers as the planets formed at different distances form the Sun where the temperatures gradients allowed the condensation of different compounds. When you consider Xenoplanets, we do not know hat they are made of exactly yet.

According to the nebular hypothesis, our solar system formed from a huge rotating cloud made mostly of hydrogen and helium gas, with trace amounts of heavier elements. The cloud, or nebula, slowly collapsed under its own gravity, leading to the formation of the sun and the planets.
The nebular hypothesis posits that our solar system formed from a large rotating cloud of dust and gas composed mostly of hydrogen and helium, leftover from previous supernova explosions. Over time, gravity caused the cloud to collapse and form a protostar at its center, with a surrounding disk from which planets eventually coalesced.
The nebular hypothesis is a widely-accepted theory that explains the formation of the solar system. It suggests that the Sun and planets formed from a spinning disk of gas and dust called a solar nebula. As the nebula contracted due to gravity, it flattened into a disk and the Sun formed at the center, while planets and other celestial bodies formed from material in the disk.

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests that the Solar System formed from nebulous material.
The most widely accepted model for the formation of the solar system is the nebular hypothesis. This theory suggests that the solar system formed from a rotating mass of gas and dust known as the solar nebula, which collapsed under its own gravity to form the Sun and surrounding planets approximately 4.6 billion years ago.
According to the nebular model of the solar system, the original cloud of dust and gas started collapsing about 4.6 billion years ago. The collapse eventually led to the formation of the Sun and the protoplanetary disk, from which the planets, moons, and other solar system bodies formed.
