How do other miners confirm a winning block?

"The miner that creates a block does not establish its legitimacy alone, because the other miners must verify both the proof of work and the transactions contained within the block. They compare the transaction data with the block’s hashed data and check the transactions against the existing blockchain history to ensure that funds were not counterfeited or spent without authorization. Their confirmations are broadcast to the network, allowing recipients and miners to accept the block and continue building on it."
