How do you know if a player is at a certain y level?

It is within a range of ~ -1.5 and +0.5. This can be tested out by using stairs, slowly walking up them, using F3 to check the y value while the command is running. The “hi” will appear even if not exactly at the desired y value.

How to detect if a player is exactly on a coordinate?

What does x y and Z mean in a command block?

To make this a bit clearer, the X, Y, and Z in the command are the center coordinates of where the command block will test for players. The RADIUS in the command is how close the player needs to be to the coordinate (the X, Y, Z specified above), to trigger the command block.
