A Boulder, or Talus, Cave is simply an enterable void or set of voids between boulders and the rock-face from which they have fallen.
Collapses within existing karst, sea or lava caves may choke the passage or chamber with boulders, and such chambers are often called "boulder chambers", but that does not form the cave, and it is not the same as a true boulder cave.
Erosional caves are formed by the action of water or wind.

A Boulder, or Talus Cave rather stretches the definition of "cave", but it's simply a void or set of voids left between fallen boulders and their source rock-face. A cave's chamber that is heavily obstructed or even terminated by collapsed rock is often called a "boulder chamber", but it's not correct to say that collapses form caves. They don't - they modify them.
Erosion is formed by weathering which then forms caves, meandering rivers, valleys and waterfalls.

No. Most caves are formed out of limestone making that false.

The Maquoketa caves in Iowa were formed through years of natural non-glacial erosion.
Wookies live in trees, not caves.

Limestone caves are formed through a process called chemical weathering. Rainwater, which is slightly acidic, dissolves the limestone rock over time, creating small cracks. These cracks then widen as more water flows through, eventually forming caves. Additionally, some limestone caves are formed through the erosion of underground rivers.

They - or it? - are normal karst caves, formed in limestone by its dissolution by water. I believe they still carry a stream: if so they are still forming.
Other way round! Water and/or air are in caves.:-) Most of the world's caves have formed / are forming in limestone.
