I have variables tracking the x and y velocity of my sprite. I tried using the atan function to find the direction of motion but was unsuccessful. Can anyone help me?

It does mean that your Yvel is affected by gravity?
I wonder why you need to keep track of direction.

It is the custom block that you can find in a lot of projects on Scratch.
You will need two variables to save x and y coordinates of sprite before it moves(X1 and Y1 in the CB) after the movement your sprite has a new set of coordinates(X2 and Y2) the CB calculates the direction and then you update the variables with the new coordinates… and so on. That is all.

I can't read that symbol after the 180. what kind of operation is that and how does Y1>Y2 fit in there?

to get direction of movement to match the sprite's direction (as regarded by Scratch) I solved it with this:

if x-velocity < 1 then movement direction = -1( arctan(x-velocity/y-velocity) +90)
else if x-velocity > 1 then movement direction = -1( arctan(x-velocity/y-velocity) -90)

By reading the original post, your looks like a miracle

Sorry if i have not helped you at all
