Yes T62s have been deployed. At least one has broken down in Ukraine. It looks like they are being used for rear area security only.
The only modern tank that uses rifled barrels is the Challenger 2, all other tanks have been smooth bore since around the 70s. The T62 is under gunned against modern tanks and generally worse in every way. There have been some updates for export models but you can't polish a 60 year old turd that much.
