Yeah, spend a few years studying digital systems design and learn how circuits work under the hood. Like how to build a CPU from transistors and program counter, and register file, and ALU, etc. That will help you understand how things like stack smash attacks and other attacks work. As well as some other vulnerabilities often not publicized.
Without an understanding of hardware, understanding vulns can be difficult/impossible in many cases.
Boot camps are fake news, to really get into cybersecurity takes many years so avoid those.

^This is the kind of digital/transistor logic I'm talking about. That's a Full Adder which is one part of an ALU in a CPU.
You also should study Radio/EM stuff because a lot of exploits I have found use weird side channel attacks that require an understanding of radio propagation or special techniques that most people would never realize was happening even if they looked at it directly like heterodyning.
After hardware/radio learn C programming and how pointers work and things you can do with those like ROP gadgets.
Cybersec is a really huge and complicated field that requires a very wide spread of knowledge and extreme paranoia to truly be good at.
