If you start from a rock-solid distro, install an adequate DE and do troubleshooting the Windows way (i.e. just reinstall and restore your data from a manual backup whenever things go haywire - which they shouldn't, anyway), you can absolutely get away with not using the Linux CLI, ever. Is this a sensible way of using a computer system? Perhaps not. Is it better than just staying on Windows 10 (provided that Linux itself addresses your needs, of course)? Absolutely!
