The transactions shown in the images you shared have been made from your trading account, not your wallet.
Well spotted! I'm not familiar with trading accounts or blockchain.com, but maybe worth checking whether there's also a 'funding account' or anything like that which allows you to actually withdraw funds?
I may be totally wrong here, but do exchanges maybe sometimes use this type of workflow?
