You are correct that keeping time (what an engineer would call "maintaining a common time base between transmitter and receiver") is necessary to play together with other musicians. But what musicians would call "feel" is what an engineer would call "phase modulation" -- whether a note is ahead of the beat, on the beat, or behind the beat; and by how much. Especially in Black American music (jazz, blues, soul, R&B, and a bunch of pop that's been influenced by those styles), there is a lot of crucial information there beyond what is conveyed in the "gridded" rhythms that are conveyed in Western musical notation. If you are not aware of this, you will still have problems playing with other musicians. From personal experience, it is anxiety-inducing to play with musicians who are ignorant of their beat placement and as a consequence have what an engineer would call "jitter" -- their timekeeping is correct on average, but on each given beat, they might be a little bit ahead or a little bit behind. You can play with a metronome for ages and never realize you're doing this wrong, as you're not consistently rushing or dragging, you're just inconsistent.
