How accurate do you have to be with the lassoo. I've tried to do this and ended up with this image

One has to be very precise.
Please post the file before any manipulation and I shall get back with a suggested workflow.
I have moved your post to a new thread so it is more visible on the forum. As hatstead has suggested, it would be helpful to see the whole before image. However, it is likely that you will be better off using a different tool such as the Magic Wand (1) to select all the white pixels. Uncheck the contiguous box (2).
When you delete the selection you should be left with just the non-white pixels on a transparent background (3):
As I said in my last reply, you should use the Magic Wand tool to turn the white background into a transparent one. Simply click on the white background and press the Delete button.
Or are you trying to do something else?

I am learning more about my PSE 2020 every day by reading posts on this forum. But I can NOT make this work. I saved the image posted by startingtopuff above and then did exactly as you mention in your reply, but the selected background does not change. What am I missing?
wchettel, dbl clk the layer in the layers panel to unlock it first (to unlock it).
Thanks, Phinny, that fixed it!
Our problem is that the file we get from what is displayed from the forum is not the original one. The checkered part does not represent transparency, it is really checkered. You can verify this by transforming the background to a normal layer and put it over a white background.
So, Greg's solution should work ok. Otherwise, you could select separately the green and black parts and copy them as layers (Ctrl J) and merge both layers to get the desired effect without checkers.
I'm multitasking at present, cooking dinner, washing up etc and have just got back to PSE. My last reply was in response to a request from Halstead to show the image before manipulation. I have now tried the magic wand and ended up with this:
With the original file, be sure to set the tolerance of the magic wand to 0.
Or try my other suggestion to select separately black and green into new layers and merge them before hiding the original background (don't flatten!).
My results were not very good with tolerance set to zero.
Much better with tolerance set to 40.
Why is this?
Wow, thank you everyone. I have succeeded in my quest, I have assumed by delete you mean clicking on the layer in the layers panel and hitting backspace? My only question now is should I save image as a .png or .jpeg
If you want a transparent background, yes, save as .PNG. I just used the Delete key on my keyboard.
Just to summarize this thread for future viewers, to clarify some confusion that I introduced, and to answer some remaining questions, here are the main points:
I have assumed by delete you mean clicking on the layer in the layers panel and hitting backspace?
Yes, the backspace and delete keys work the same in this case.
My only question now is should I save image as a .png or .jpeg
As mentioned earlier, jpeg files do not support transparency, so as wchettel has responded, you may use the png format to save the file with transparency. You can also save as a tiff file for transparency.
Hope I am not confusing anyone any further with this post. 😀
You might consider installing the free add-on KillWhite that does just that: replaces white with transparency. This can work well for complex pictures where it might be difficult to select the white using the PSE tools. It is installed in the Plugins folder (named KillWhite.8bf) and appears in your PSE Filter list under "Mike and Yael". There are no settings; simply click KillWhite.
Note that you can apply it to just a selected area of the picture.
Since the white is replaced with transparency, you would have to apply the filter either to a duplicate of the Background layer or else a renamed Background layer.

For demonstration purposes, here I ran KillWhite and put the result over a color background.
