Most of them, no.

When the war ended, the armored vehicles were driven or transported to a few depots around, mainly Germany, whilst folks figured out what the heck they were going to do with them all.

By the time the war ended, the US Army had decided to standardize on the M4A3(76) w/ HVSS as the one and only Sherman variant that they would use in the future, The light tank would be the M24, and the heavy tank the T26E3, later to be known as the M26 Medium

Only about four and a half thousand of these tanks were built, out of the nearly 50,000 Shermans produced. Then you add on a bunch of M5 light tanks and the like, also considered obsolescent.

This left a whole hell of a lot of M4s still out there, most of which were in Europe. A lot of the 1,300 or so M4A1 (76s) ended up equipping the French Army after the war. The Soviet ones got turned into tractors. With the British doing well with their domestic tank production, they had little cause to keep theirs, a lot ended up going to the Italians.

Tanks scattered around the Pacific Islands were gathered together and shipped to Japan for repair or reconstruction, which proved handy when the Korean situation broke out. They also started to equip the new Japanese Arm...erm.. ground self defense force.

Indeed, many of the European countries rather needed tanks, and they basically came from two sources. US or USSR. Older 75 and 105mm M4s were modernised under the MDAP program, maybe a thousand of them, going to countries like Denmark, India or Yugoslavia (Oddball's tanks from "Kelly's Heroes" are Yugoslav MDAP upgrades). Some countries, like Netherlands just took them as they were without upgrade. The Portuguese were a bit odd, they imported Grizzlies from Canada after the war.

Eventually more countries ended up getting some. Over time more countries grabbed them, such as Egypt from British stocks or Argentina and Brazil from (mainly) American.

And, of course, a surprising number got turned into monuments and the like.
