Just bought an indoor trainer and was thinking it was a good time to update my rear cassette and chain since they were pretty worn.
Changed the ratio on the cassette so went with the biggest ring to biggest ring + 2 rivets method i found in youtube videos for chain length. Im learning to wrench on my bike as i go (first time doing something other than pumping air in my tires or adjusting handlebars) and have close to zero experience whatsoever wrenching on a bike.
Is it too tight ? There is still a bit of play in the rear derailleur when using biggest to biggest ring but it seems pretty extended.
Plus, the play between the derailleur and cassette seems awfully small, is that normal ? Any help is extremely appreciated!

Play between cassette and derailleur
I think the bigger issue here is that you are exceeding the max sprocket size on that derailleur.
Is that a short or long rear derailleur?
Cross chain much?
You issue (if I’m seeing this correct) is that you bought too big of a cassette for what your RD (rear derailleur can handle. Groupsets (shifty bits) of this era usually max out at 28tooth rear cog. This looks bigger than that likely 34. Just return the cassette (before you use it) and get a 28 tooth one. Then after you’ll probably have to take 1-3 links out of the chain.
Capacity on that derailleur is most likely 11-28
You have either to get a long cage derailleuer, or just the long cage and swap it, or a smaller 28 teeth cassette, or you can use one of those wolf tooth road link derailleuer extender
An Acera 3020 rear derailleur will work with your shifters and allow you to use that cassette and even bigger if you want. Any long cage Mega 9 derailleur will also work. You’ll still need to add some links to that chain.
Chain too short, yes. But you should never be in those gears anyway. Never big and big and never small and small.
Looks fine.
