Indeed. The French navy helped in a significant way as it in some part slowed the flow of supplies from Britain and helped the colonies defend some of their port cities more strongly.
Also, Britain’s desire to be a global power also aided the American victory towards the later years of the war (as it was spread thinly fighting a few enemy countries at once around the world). I believe the war was mostly won a few years before 1783, and the latter part more the formality of Britain growing tired spending resources to support the fighting, politically convincing Parliament of the need to end things, and then negotiating formal peace with the US, France, and Spain.
