This is a very important question and the answer is very simple, but fundamental:

<ol>
<li>Run: create a new container of an image, and execute the container. You can create N clones of the same image. The command is:
<code>docker run IMAGE_ID</code> and not <code>docker run CONTAINER_ID</code></li>
</ol>

<a href="https://i.stack.imgur.com/AgpZe.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/AgpZe.jpg" alt="enter image description here"></a>

<ol start="2">
<li>Start: Launch a container previously stopped. For example, if you had stopped a database with the command <code>docker stop CONTAINER_ID</code>, you can relaunch the same container with the command <code>docker start CONTAINER_ID</code>, and the data and settings will be the same.</li>
</ol>

Explanation with an example:

Consider you have a game (iso) image in your computer. 

When you <code>run</code> (mount your image as a virtual drive), a virtual drive is created with all the game contents in the virtual drive and the game installation file is automatically launched. [Running your docker image - creating a container and then starting it.]

But when you <code>stop</code> (similar to docker stop) it, the virtual drive still exists but stopping all the processes. [As the container exists till it is not deleted]

And when you do <code>start</code> (similar to docker start), from the virtual drive the games files start its execution. [starting the existing container]

In this example - The game image is your Docker image and virtual drive is your container.

<code>run</code> command creates a container from the image and then starts the root process on this container. Running it with <code>run --rm</code> flag would save you the trouble of removing the useless dead container afterward and would allow you to ignore the existence of <code>docker start</code> and <code>docker remove</code> altogether.

<a href="https://i.stack.imgur.com/mxSq2.png" rel="noreferrer"><img src="https://i.stack.imgur.com/mxSq2.png" alt="enter image description here"></a>

<code>run</code> command does a few different things:

<pre><code>docker run --name dname image_name bash -c "whoami"
</code></pre>

<ol>
<li>Creates a Container from the image. At this point container would have an id, might have a name if one is given, will show up in <code>docker ps</code></li>
<li>Starts/executes the root process of the container. In the code above that would execute <code>bash -c "whoami"</code>. If one runs <code>docker run --name dname image_name</code> without a command to execute container would go into stopped state immediately. </li>
<li>Once the root process is finished, the container is stopped. At this point, it is pretty much useless. One can not execute anything anymore or resurrect the container. There are basically 2 ways out of stopped state: remove the container or create a checkpoint (i.e. an image) out of stopped container to run something else. One has to run <code>docker remove</code> before launching container under the same name.</li>
</ol>

How to remove container once it is stopped automatically? Add an <code>--rm</code> flag to <code>run</code> command: 

<pre><code>docker run --rm --name dname image_name bash -c "whoami"
</code></pre>

How to execute multiple commands in a single container? By preventing that root process from dying. This can be done by running some useless command at start with <code>--detached</code> flag and then using "execute" to run actual commands:

<pre><code>docker run --rm -d --name dname image_name tail -f /dev/null
docker exec dname bash -c "whoami"
docker exec dname bash -c "echo 'Nnice'"
</code></pre>

Why do we need <code>docker stop</code> then? To stop this lingering container that we launched in the previous snippet with the endless command <code>tail -f /dev/null</code>.

If thats the case, what does:

<pre><code>docker start

do?
