Why does Git say I have an error on git push when I shouldn't have one at all?

Question

git

1) Did a "git init" in the local folder
2) Created a remote repository on GitHub
3) Created a .gitignore file in the local folder (node_modules, src)
4) Added a .gitignore file to the local repository
5) Made a commit to the local repository
6) Linked remote repository with local "git remote add origin { link }"
7) Pushed changes from local repository to remote "git push origin master"
Got the following picture:

Answer 1

were there any commits on the remote repository before git push?
if yes, then before the first local commit, you need to do git pull origin master.
you can do this (but .gitignore will be deleted, and I'm not responsible for other files)

git pull --force origin master
git push -u origin master

well git push --force -u origin master, or like this: but all changes will be erased remotely.
