Yes, whenever a new block is mined, miners have to create a candidate block. This candidate block includes all the transactions that have not been mined yet. If a miner was trying to mine a block and failed, she will check which transactions have been included in the winning block. Whatever transactions is leftover becomes part of this new candidate block.
If you want a deeper explaination on this, I wrote an article called Blockchain: what is mining? That explains this concept :)
