Its not so much a skill issue, more so phone repair stores are the scams. they break stuff that wasn’t broken in the first place and get you to come back with the that issue or say it was also broken. Source: used to work in the phone repair industry and knew people who did this on the regular and is a standard.

I’ve done repairs on all my phones. New buttons, screens, batteries, ports, etc. I’ve never caused an unforeseen new issue by doing so.

What you describe is literally a skill issue though, if they’re breaking unrelated components.
