No, the average 155mm round with the M777 howitzer is outranged by the Russian gun in similar caliber by about 17%.
And no indirect fire weapon hits within “few meters” except with precision munition.
Russia has them, Ukraine doesn’t. 40,000 rounds are nothing for this sort of conflict on top of that.
Ukraine is receiving an undisclosed number of 155mm Excalibur shells. Not only is their range awesome and superior to Russian weapons, they are GUIDED shells:
"The M982 Excalibur is a 155-mm extended range guided artillery shell. The Excalibur was developed and manufactured by Raytheon Missiles & Defense and BAE Systems AB.
"Excalibur is guided through the GPS and can hit targets up to 60 km away. And in December 2020, during the tests, the US Army successfully hit the target at a distance of 70 km. The weight is 44 kg, and the weight of the warhead is 22 kg. "Experience from Iraq has demonstrated the high accuracy and effectiveness of these weapons – 92% of hits were with an error of less than 4 meters."

And this is just one of the types of shells Ukraine is receiving, with Ukraine possibly receiving even more advanced shells than these from Canada, the US and other countries.
I have already seen a picture of destroyed Russian artillery with artillery damage concentrated both on the artillery and closely around it, unlike the moonscapes that are ordinarily caused by Russian and Ukrainian standard artillery.
These, combined with Ukraine's 1,600+ other artillery systems they possessed before the war, as well as the undisclosed numbers they are receiving from other countries, absolutely gives Ukraine an edge.
Russia might have thousands of tubes, but it doesn't do them any good since they refuse to actually engage in proper tactics, concentrate their fire, and their troops piss themselves and run for their lives at the slightest opposition!
