For a beginner, probably not. Bigger is easier, as the size/volume will be more forgiving for any mistakes you make with water quality, temperature, etc. However, if you cannot afford to get something larger, heat and frequent water changes are ESSENTIAL to your betta's health. Below are the generally accepted MINIMUM water change schedules according to volume (by leading authorities in betta keeping)...of course, more water changes is always preferable:
1 quart or less: 100% every other day
1/2-gallon: 50% every other day
1 gallon: 50% every week
2 gallons +: 50% every two weeks, but preferably at least 25%+ per week
Filtration will give you a little bit of a break on these schedules.
