Even though Arbitrum transactions are still settled on Ethereum, only raw transaction data is submitted to Ethereum, with execution and contract storage occurring off-chain. This makes the gas fee required on Arbitrum much smaller than on the mainnet, and contracts are fully compatible with no gas limit.
