Billions are so big they're hard to get your head around. They just feel "big." So here's a more tangible comparison:
Let's say 1 nanometer (nm) = $1
1 nanometer is on the scale of atoms and molecules (about 10 hydrogen atoms side by side).
$100,000 is more than I make as a professor in a year.
100,000 nm (100 micrometers) is about the thickness of a coarse human hair
At $1 million net worth, you're a millionaire.
1 million nm (1 millimeter) is about the thickness of a pencil line
1 billion is a thousand millions. It's HUGE. There are fewer than 3,000 people in the world with a net worth over $1 billion (USD)
1 billion nm is 1 meter, about as big as the distance I go in a large step

Bezos is the "poorest" of the billionaires listed in the linked post, worth $241.9 billion
241.9 billion nm is more than halfway around an Olympic running track (400 m)
The US median net worth is about $190,000
Musk's is $394.2 billion
Musk has almost made it around the Olympic track while 50% of the US has gone about two hairs' breadth
