I have a 2013 Suburban with the 5.3 and I have the P0521 code. I’ve been told it’s the oil pressure sensor. The engine isn’t knocking or ticking as of now. I have heard that the oil pressure sensors on these late 2000s-2010s go out frequently. I also have a 2007 Silverado which when I bought also had issues with the oil pressure gauge. Is it common for them to go out?

Who told you that? While possible there are a number of possible causes for that code:

Dashboard oil pressure gauges in general can frequently be unreliable. Your actual oil pressure can be checked with a mechanical test gauge.
