POst a link to give an example of where you are at, and then we can maybe help.
Going by the link you gave to the lotki track, it`s actually a very simple groove they got going there.
There`s either a minor velocity movement in the kicks or a little delay, that gives that kick groove a kinda live feel.
And the hat pattern is also pretty simple. Possibly sidechained to the kick slightly to again, give it a little ducking and movement, or again it`s just subtle velocity programming.
There`s some little snappy hits in there too, but again, they are sparse and simple.

I think as a rule keeping things simple, but not having static velocities is a good way of keeping beats very fluid and natural.
Also be aware of counterpoint, or sound and return.
ie the kick needs a counterpoint to balance against, be it a hat or clap or whatever, and it`s how you break down the countering, whether you do it every quarter bar, or half bar, or whatever, that sets up the groove.

Being able to play the drums, or understanding drum theory also helps:)
