Canon film era EOS lenses use the same EF mount used today. Almost all Canon brand, as opposted to independent lens brands, will work with the current DSLRs. There may be a few that don't.
You do need to keep in mind that DSLRs, while they look like 35mm SLRs, do not all have the same size sensors. The most common are significantly smaller than a 35mm negative, being roughly the size of the old "half-frame" 35mm format. As a result, your lenses will seem "more telephoto" on the common DSLR than they do on film. When used on the common Canon DSLRs they will seem like lenses that were 1.6x longer than their actual focal length. As a result, an kit of film lenses that served well end up lacking any decent wide angle when used with the common DSLR. This difference is often referred to as the camera's "crop factor".
There are a few so called "full frame" DSLRs on the market abd Canon offers some. These are significantly more expensive, but had sensors roughly the same size as classic 35mm full frame film.
BTW, a Canon EOS Rebel 2000 would not have come with an 18-58mm lens. No lens of that FL range was made in EF mount. It more likely came with one of the several 28-80mm lenses that Canon offered.
