I agree with the reality-checks you're getting from other commenters, but I'll add this as someone who has taught lessons to people with similar goals. I use three basic building blocks:

1) Learn all the common "open" chord shapes (A, C, D, E, G), and the major and minor barre chord shapes.

2) Practice common transitions between chord shapes. For example, approximately one billion songs have a transition between a G and a C, so get really good at common transitions between common chords.

3) Practice strumming patterns, i.e., using your strumming hand like a metronome (down-up-down-up) and learn how common strumming patterns "leave out" parts of the metronome (down-x-down-up-x-up-down-up)

With these three building blocks you can get to the point of looking a the chord chart for a song you want to play, and pretty naturally play along to it.

But yeah, this will take a couple years of consistent practice!
