It’s clear you haven’t used linux.
Windows: open edge, go to google, type the package you want, scroll past ads, download random executable from internet, execute, click through wizard, open program.
Linux: open package manager, search package you want, click install, open program.
For a lot of distro’s you don’t need to use a terminal to install things if you aren’t comfortable with that. While I believe learning to use a commandline a little bit will always be beneficial, you really don’t havo to. Take a look at linux mint for example, which has a “store” for packages.
