I think I sent ETH on the wrong network. Did I lose my funds?

I have very little crypto knowledge so I apologize in advance. Long story short I was attempting to transfer funds from coinbase to an online casino. I have done this plenty of times with BTC. I buy BTC on coinbase, send it to the wallet the online casino provides, and fund are sent.

This time I decided to use ETH for the first time. Purchased ETH on coinbase and initiated a transfer to the online casino. Coinbase asked what network I wanted to send it on. I selected the “base” network because Coinbase said the fees were the lowest.

It has now been over an hour and funds haven’t arrived. In general with BTC funds are usually available within 5-10 minutes. I was doing some research and it seems ETH can’t be sent on base network? Is this accurate? Are my funds gone? Thanks for the help.
