Non-PC owner thinking about getting a SteamDeck

Please forgive my ignorance, but I haven't owned a PC in over a decade so I'm out of my element here. I am a casual console gamer, but I really like the idea of a SteamDeck; especially since there was re some PC-only games that look cool that I'd like to play. Is it worth it for someone like me? Do I need any kind of PC knowledge or something? Will I get just as much out of it as most people? Again, please forgive my ignorance. Thanks!
