This is an effect of the channel reserve, see: https://docs.rs/lightning/latest/lightning/util/config/struct.ChannelHandshakeConfig.html#structfield.their_channel_reserve_proportional_millionths.

The channel reserve is enforced to ensure each counterparty always has something to lose, if they were to try to cheat. By default, the channel reserve is 1% of the total channel capacity, and LDK sets a hard minimum of 1000sats.
