This is correct. The idea is that money spent by the wealthy enjoying themselves or making themselves wealthier through investments eventually reaches the poorest - in some form. Quite why we've persuaded ourselves we need to do this through a remote & deaf middleman is anyone's guess, when governments we elect could just direct money through policies we can all argue about and nudge in our own small ways.
