I run yay -Syu and it says everithung is up to date, then for the first time since installing the OS (like 1 week) u run yay upgrade and there is 102 things. Should I press ENTER?
It lists every package with the word upgrade in it’s name or description, so does diddly squat.
If you want to update your system, just run yay by itself.
When running yay by itself, like I just did right now, it should look something like this…
[wombat@endeavouros ~]$ yay

Press enter and follow any prompts.
so do I upgrade or just keep using just yay?
Simply run yay. nothing more to do
Just yay, upgrade is a Debian thing.
Just use yay by itself to update your system and packages.
Run sudo pacman -Syu to update packages installed from the official repos.
Run yay --aur to update packagees installed for AUR.
Or as has been mentioned above, just:
yay
to update packages installed from official repos and those installed from AUR.
For more info, consult:
man pacman
man yay
https://wiki.archlinux.org/title/Special:Search
A quick cheat-sheet for yay…
Install the packages with:
yay -S package_name
Remove packages with:
yay -R package_name
To remove/delete a package with its dependencies:
yay -Rns package_name
Upgrading/Updating AUR packages only:
yay -Sua
Upgrading/Updating ALL packages:
yay
I would add yay -Yc to remove orphan packages from time to time if you remove packages often.
Other than that use yay because you are so happy to get cutting edge new free software 
I use yay because you only need to type in 3 letters. ( I’m lazy ) 
I was just about to do that, you read my mind
I use the up key lol
Added
alias u='eos-update'
alias ua='eos-update --aur'
to my ~/.bashrc.
Now I update with command u or ua depending on do I want AUR updates too or just the native updates.
In your case I might recommend
alias u='eos-update --aur'
Same here. Did you stole my aliases 
Very likely those aliases are quite obvious if short commands are the goal…
If I were to setup aliases like this I’d add a few surprise ones for people not meant to be there, otherwise I can spare the 2 seconds
Indeed. I’m too lazy to type eos-update --aur
Which is why I use up, 95% of the time it is yay, otherwise it is very close
