No. A ringstand is a stand with a base with a large pole sticking out of it. that you can attach rings to. A wire mesh is usually placed on the ring for setting a beaker to be heated. A test tube clamp can be attached to the ring stand to hold a test tube, for say, heating it in a hot water bath.
Test tubes are typically placed in a test tube rack to ensure they remain upright and stable during experiments or when storing. The rack also helps prevent the test tubes from rolling or breaking. It is important to use a rack that is the appropriate size for the test tubes being used to ensure a snug and secure fit.
A test tube holder, also known as test tube clamp or test tube rack, is used to hold a test tube in place when the tube is hot or should not be touched. It allows safe handling of test tubes during heating or when conducting chemical reactions.

It is not recommended to place a hot test tube directly into a test tube rack as this can cause damage to both the test tube and the rack. It is advised to allow the test tube to cool down before placing it in the rack to prevent any accidents or mishaps.
Assuming you're talking about a wooden or metal 'rack' which is capable of holding a few test-tubes. They are simply a safe way to allow test tubes to stand upright without falling over. A hot test tube, or one holding corrosive chemicals - is safer supported by a rack - than being held in someone's hand !

A test tube holder is a device to ...wait for it...hold test tubes ! ;-) Usually a rack or clamp that keeps them upright (& full if in use).
Test tube racks are used to support the test tubes but unlike the test tube holder, it can store the test tubes without anyone who will hold the rack... hope this helps!
A test tube holder or rack is used in a laboratory to hold or support test tubes containing chemicals or other contents awaiting further operations. Although it is called a test tube holder, it is also used to hold/support pipettes, etc. Since a test tube has a rounded bottom, it cannot stand by itself; the rack is a convenient and necessary piece of laboratory equipment for the storage of test tubes.
