Can the buyers or sellers in the smart contracts be the miner also?

Yes.

Like someone be the player and also be the verifier?

In Bitcoin, everyone verifies. All players are also verifiers. There are no players who are not verifiers. The miners do not have any special role in verification. Nobody depends on miners to verify anything.
The job performed by miners that is not performed by non-miners is a sequencing of transactions that results in the production of confirmations of those transactions. Confirmations are different from verification.
