you and I have a lot in common - playing both table tennis and regular tennis. My answer to this question (from years of observing the effects of playing both sports) is both yes and no. Some things are the same (and help across both sports) and some are different and don't help that much.
Balance - both require good balance and using your non-hitting hand to help you maintain your balance when having to reach for a shot.
Hand-eye coordination - both require you to concentrate on, and keep your eye on, the ball.
Recognizing spin - your ability to recognize what kind of spin your opponent puts on the ball helps in both sports.
Stamina - high level tennis requires greater physical strength and stamina. You'll have to be in better shape and more fit to reach higher levels of the game.
Stroke/Technique - This is most notable to me. In tennis, I need a much different kind of stroke (more loopy, different contact point, different follow through, etc.) in tennis than in table tennis. In table tennis I can get away with using more wrist to hit the ball and I need to apply much less effort into contacting the ball in table tennis. What I find if I am playing more tennis than table tennis is I hit a lot of shots past the end of the table in table tennis. Oppositely, I end up using too much wrist in my tennis strokes if I've been playing more table tennis.
Game Pace - the back and forth action in table tennis is (on average) a lot faster than in tennis, so you have to be ready to hit your next shot much sooner in table tennis than in tennis and you sometimes adjust your strategy in table tennis to allow more time to recover for your next shot than you would in tennis (though sometimes the same strategy applies in tennis as well if you've been pulled far off the court).
