Congratulations

No bro, haptic feedback means you'll feel little vibration when you press back, recent, back button or type.
If you're using Samsung keyboard, you'll see a gear icon on keyboard. Tap that and then go to 'keyboard layout and feedback' --> key-tap feedback --> Check if vibration option is there or not.
I'm using Android 8.1 so it might be little different.
