Yes true and French money made the Swedish Army possible during the 30 years war. Sweden a nation with nearly 2 million inhabitants and 250 000 soldiers...
Indeed, but what is also true is that this wasn´t a war where all of Europe (+- Russia) fought against France. It was more like everybody against Habsburgs (even catholic France, because of the political reasons). Other than that in the timeframe.
Hundred years war. My God did France messed that one up. It won, barely, in the end. Saved by woman who was seeing ghosts. Personally I consider this a victory, but I hope we can agree on that it was tough one.
Wars in Italy - temporarily France won, but later was pushed back and back. Here, I would say France just had too many enemies. Something remained in it´s hands, but not as much as it hoped.
Thirty years war - we discussed that. France came there quite late and I have to admit it subsidized Sweden (which didn´t helped us, Swedes only looted half of Prague, but ok). Well, France didn´t loose, but Austria technically gained control over the whole HRE. The peace mainly meant status quo. Some countries lost (Bohemia), some gained (Sweden, Austria).
War against the Nehterlands - some gains, ok. But not too much.
War of the Spanish Succession - Prince of France became the king of Spain, but he could never united it. Also, France lost some territory to Austria. So draw in the best.
French revolution - well, the enemies were French so this is as much win as it is lost, it depends who do you favour.
Napoleonic wars - temporarily big gains, but as Napoleon became too greedy, everybody united against him. His ambitions led him to Russia, where he lost pretty much all his soldiers (btw there are new facts about this - maybe it wasn´t winter, but bugs with diseases which killed most of his soldiers).
End of timeframe. After it, it got only worse. During the timeframe, France was quite strong on the paper, but usually it couldn´t achieve it´s ambitions (quite often it gained something but not as much as it can). I agree it´s failures are often made bigger than they were, but I wouldn´t glorify it either.
