Is wholesaling solo as an absolute beginner really feasible?

I just learned about this from those people on Instagram and YouTube all with the click baity titles saying "make 10-20k in less than 30 days with no money". I assumed it was too good to be true at first but my interest was peaked enough to start doing research. I see it's a legit practice and way to make money but after perusing this sub for a little bit I see people talking about having to send out hundreds of calls, letters, or visit hundreds of houses. I realize it can take a lot of time to even find a potential lead but is this really feasible for somebody with basically no money to throw at this and somebody with no experience (besides having purchased my own home) and would be completely on their own? Am really curious because even one successful deal would be absolutely life altering for me.
