i just wanna make sure i understand this fully.
cc-by 4.0 and oga-by 3.0 allow a person to use the spritesheets in a closed source game engine like clickteam fusion 2.5, but cc-by-sa 4.0 and any gpl derivative do not. is my interpretation correct?

Not quite.
GPL is likely the most difficult to use in a closed-source project. However, it is still possible to do so. It depends on how the GPL-licensed components are used. There are ways of incorporating content that would trigger the GPL linking requirement, meaning anything alongside the GPL assets would necessarily also be GPL. This is a topic of huge contention, so I will say it is unlikely you will find a sollid answer on this. I am not equipped to give much more advice than my statement above on GPL. I personally think it is the worst license we accept here on OGA just for how difficult it is to work with, even in non-commercial open-source projects.
CC-BY-SA is also surrounded by contention on the topic of it's viral effect, though to a far lesser degree. That is, does it infect the rest of the project (including code) with the CC-BY-SA license? I can fairly confidently answer "no, it does not make the project's code also CC-BY-SA".
Any derivatives of CC-BY-SA artwork must also be CC-BY-SA. It is one thing to take music, sound effects, 3D models, or 2D graphics and modify them into some new form of that same medium. That makes sense, but morphing such assets into programming code? That would be truly bizzarre. Game code may reference such assets, it may utilize such assets, but I have never seen game code made from such assets. Therefore, the game code would not be required to be licensed CC-BY-SA just by using CC-BY-SA licensed assets.
I say I am confident in this opinion, but if you're looking for absolute surity, noting short of hiring a lawyer will do, I'm afraid. People will be disagreeing about this interpretation of CC-BY-SA forever, as demonstrated by the unending discussions about this topic already scattered across OGA:
--Medicine Stormproblem is that the apritesheets are kind of "locked into" the executable file by clickteam fusion. i could include the sprite sheets as a seperate file, but it would not be the actual image used by the game code. which makes me wonder if having the images embedded in the exe would be a form of drm? i know this stuff has been discussed ad-nauseum so sorry to beat a dead horse.
for a while i was only using cc0 stuff from here because atleast i knew that i wasn't gonna be out of pocket by just attributing and not worrying about the technicalities of the game engine. the share alike licenses don't work for me, i don't want to re-release an edited sprite where all i did was move the character's eyeball or some such.
