I don't understand how to write Rails routing.

When I was looking at Rails routing, there was a description that I didn't understand, so I would like to ask you a question.
Am I correct in understanding that I will go to see the sample#show when I transition to /sample(ya/sample/hoge)?

 resource:sample,controller::sample,only:[:show] do
  get '*other', to: 'sample#show'
end

By the way, this sample#show is going to read SPA files

def show
  render file:Rails.public_path.join('dist', 'web', 'sample', 'index.html', layout:false
end

It is written as follows:

/sample
/sample/confirm
/sample/complete
There are screen files equivalent to .
