Nintendo switch lose my games? (Help)

[Lowgs92]

Hey guys so I bought a Nintendo switch at a gas station from a guy who wanted a pack of smokes and asked me if I gave him 5$ he would give me the switch.. I said hell even if it’s broken or fake it’s 5$ what do I have to lose. Sure as S**t it worked with a ton of games on it digitally downloaded. I assume it is stolen or maybe not maybe it’s his kids or something who knows. Any ways my question is this, it keeps asking me to system update and I’m wondering if I do will I lose the digital games on it if it was stolen and someone got a new switch and made their new one the primary system and reported my unit stolen to Nintendo? There is parental lock on it but it doesn’t effect me playing the games or anything like that. So I’m wondering 1) will I lose the games if I system update? And number 2) is their a way to take off the parental lock without having the password and resetting the console? Thanks again for answering
