On-chain transaction fees are always one of painful experience for blockchain users including gamblers. It is similar to Play-to-Earn games on expensive chains like Etheruem ERC-20 chain and maybe Binance Smart Chain some weeks when BNB hit $500 to $550.
When there are lot of transactions then the fees goes up really high and players find it hard to afford specially at the ETH network because for a small transfer also you have to pay huge gas and big whales in order to confirm their tx pay double or more then average which boost the fees even more.But yes you can surely try it on weekends when there is less volume but it's open 24*7 so can't say it will stand true.
