When opening a LN channel using LND, what does 'push-amt' do?
The money now belongs to the counterparty in the channel you opened. In every one of your channels, whether you opened them or they were opened to you, "local balance" refers to your spendable/forwardable balance and "remote balance" refers to the counterparty's.

Don't worry though, if your node stays online reliably, then others will open channels with you, giving you inbound capacity. At this stage there's not much else you can do.
