Miners add Block to Block chain right?
I read this link https://learnmeabitcoin.com/glossary/candidate-block and it is mentioned "Nodes (mining nodes) select transactions from their memory pool to form their own candidate blocks."

That mean if I am a miner can I add my transaction to candidate block?
What is the main use if Candidate block?
This next block to be added called Candidate Block? But, I had read that the next block to be added is called winning block.
Is there any article(in simple language not much technical) where I can read more about this?
Can someone please explain me more on this?

Was reading about mining and got struck at this word. Please help.
