If gravity could ever overcome expansion, then there would be some period where expansion was happening, but the rate of expansion was decreasing, eventually followed by expansion stopping, then contraction happening and the rate of contraction increasing. There would not be any period in which the rate of expansion was increasing.
(When you throw a ball up, after you release it, there’s a period of time when the ball is moving up, but it’s speed is decreasing, then it reaches the apex, and it start falling down and it’s speed increases until you catch it. There is no period where it upward speed increases.)
Current observations show not just that expansion continues, but that the rate of expansion is increasing.
(Not only has the big bang thrown the ball, but the ball’s upward speed is increasing.)

I genuinely appreciate you taking the time out of your day to respond to me nicely and not just take the piss out on me. Thank you.
